The dimethylpalladium(II) complex PdMe2(9S3)(8) has been obtained similarly from PdMe2(tetramethylethylenediamine), but Pd(CH2SiMe3)2(9S3)(9) could not be isolated in a pure state. Crystals of 5 are orthorhombic, space group Pbca, with a = 12.047(1) A, b = 17.660(2) A, c = 16.854(2) A, and Z = 8. The structure was solved by heavy-atom methods and refined by least squares analysis to R = 0.031 and R, = 0.046 for 2498 unique observed reflections. The platinum atom is bound to two sulfur atoms of bidentate 9S3 and to two cis-phenyl groups in an almost planar array. The macrocyclic thioether adopts an exodentate conformation such that the uncoordinated sulfur atom points away from the metal atom, in contrast to the more usual endodentate conformation found in PdX2(9S3) (X = C1, Br). At room temperature, the 9S3 CH2 resonances in the 1H and 13C{H} NMR spectra of 1-7 are broad; variable-temperature NMR studies of 2 and 4 suggest that this is caused by exchange of free and coordinated sulfur atoms. Complexes 3 and 4 react with halogens to give diorganoplatinum(IV) salts [PtXR2(9S3)]X [R = CH2SiMe3, X = I(l0), Br(11); R = CH2CMe3, X = I(13)], and 1 and 2 oxidatively add methyl or ethyl iodide to give triorganoplatinum(IV) salts [PtR2R’(9S3)]1 [R = R’ = Me(14); R = Et, R’ = Me(15); R = R’ = Et(16)]; in these products 9S3 is probably tridentate. The palladium(II) complex 8 likewise adds methyl iodide to give [PdMe3(9S3)]I(17), which can be converted into a nitrate salt [PdMe3(9S3)]N03(18). These compounds show no tendency to reductively eliminate ethane, and they are the first isolable organopalladium(IV) complexes that do not contain a nitrogen donor, thus demonstrating the ability of endodentate 9S3 to stabilize octahedral or pseudooctahedral geometries." name="eprints.abstract" /> <meta content="1993" name="eprints.date" /> <meta content="published" name="eprints.date_type" /> <meta content="Inorganic Chemistry" name="eprints.publication" /> <meta content="32" name="eprints.volume" /> <meta content="10" name="eprints.number" /> <meta content="1951-1958" name="eprints.pagerange" /> <meta content="10.1021/ic00062a013" name="eprints.id_number" /> <meta content="TRUE" name="eprints.refereed" /> <meta content="0020-1669" name="eprints.issn" /> <meta content="http://dx.doi.org/10.1021/ic00062a013" name="eprints.official_url" /> <meta content="(1) Permanent address: Department of Chemistry, The University of Tasmania, Hobart, Tasmania 7001, Australia.

The dimethylpalladium(II) complex PdMe2(9S3)(8) has been obtained similarly from PdMe2(tetramethylethylenediamine), but Pd(CH2SiMe3)2(9S3)(9) could not be isolated in a pure state. Crystals of 5 are orthorhombic, space group Pbca, with a = 12.047(1) A, b = 17.660(2) A, c = 16.854(2) A, and Z = 8. The structure was solved by heavy-atom methods and refined by least squares analysis to R = 0.031 and R, = 0.046 for 2498 unique observed reflections. The platinum atom is bound to two sulfur atoms of bidentate 9S3 and to two cis-phenyl groups in an almost planar array. The macrocyclic thioether adopts an exodentate conformation such that the uncoordinated sulfur atom points away from the metal atom, in contrast to the more usual endodentate conformation found in PdX2(9S3) (X = C1, Br). At room temperature, the 9S3 CH2 resonances in the 1H and 13C{H} NMR spectra of 1-7 are broad; variable-temperature NMR studies of 2 and 4 suggest that this is caused by exchange of free and coordinated sulfur atoms. Complexes 3 and 4 react with halogens to give diorganoplatinum(IV) salts [PtXR2(9S3)]X [R = CH2SiMe3, X = I(l0), Br(11); R = CH2CMe3, X = I(13)], and 1 and 2 oxidatively add methyl or ethyl iodide to give triorganoplatinum(IV) salts [PtR2R’(9S3)]1 [R = R’ = Me(14); R = Et, R’ = Me(15); R = R’ = Et(16)]; in these products 9S3 is probably tridentate. The palladium(II) complex 8 likewise adds methyl iodide to give [PdMe3(9S3)]I(17), which can be converted into a nitrate salt [PdMe3(9S3)]N03(18). These compounds show no tendency to reductively eliminate ethane, and they are the first isolable organopalladium(IV) complexes that do not contain a nitrogen donor, thus demonstrating the ability of endodentate 9S3 to stabilize octahedral or pseudooctahedral geometries.</p></div><table style="margin-bottom: 1em" border="0" cellpadding="3" class="not_ep_block"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/259901.html">250000 Chemical Sciences > 259900 Other Chemical Sciences > 259901 Organometallic Chemistry</a></td></tr><tr><th valign="top" class="ep_row">Collections:</th><td valign="top" class="ep_row">UNSPECIFIED</td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">2863</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">Prof Allan J Canty</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">14 Jan 2008 15:09</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">18 Jan 2008 13:32</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=2863;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&eprintid=2863">item control page</a></p> </td></tr></table> </div> <!-- InstanceEndEditable --></td> </tr> <tr> <td><!-- #BeginLibraryItem "/Library/footer_eprints.lbi" --> <table width="795" border="0" align="left" cellpadding="0" class="footer"> <tr valign="top"> <td colspan="2"><div align="center"><a href="http://www.utas.edu.au">UTAS home</a> | <a href="http://www.utas.edu.au/library/">Library home</a> | <a href="/">ePrints home</a> | <a href="/contact.html">contact</a> | <a href="/information.html">about</a> | <a href="/view/">browse</a> | <a href="/perl/search/simple">search</a> | <a href="/perl/register">register</a> | <a href="/perl/users/home">user area</a> | <a href="/help/">help</a></div><br /></td> </tr> <tr><td colspan="2"><p><img src="/images/eprints/footerline.gif" width="100%" height="4" /></p></td></tr> <tr valign="top"> <td width="68%" class="footer">Authorised by the University Librarian<br /> © University of Tasmania ABN 30 764 374 782<br /> <a href="http://www.utas.edu.au/cricos/">CRICOS Provider Code 00586B</a> | <a href="http://www.utas.edu.au/copyright/copyright_disclaimers.html">Copyright & Disclaimers</a> | <a href="http://www.utas.edu.au/accessibility/index.html">Accessibility</a> | <a href="http://eprints.utas.edu.au/feedback/">Site Feedback</a> </td> <td width="32%"><div align="right"> <p align="right" class="NoPrint"><a href="http://www.utas.edu.au/"><img src="http://www.utas.edu.au/shared/logos/unioftasstrip.gif" alt="University of Tasmania Home Page" width="260" height="16" border="0" align="right" /></a></p> <p align="right" class="NoPrint"><a href="http://www.utas.edu.au/"><br /> </a></p> </div></td> </tr> <tr valign="top"> <td><p> </p></td> <td><div align="right"><span class="NoPrint"><a href="http://www.eprints.org/software/"><img src="/images/eprintslogo.gif" alt="ePrints logo" width="77" height="29" border="0" align="bottom" /></a></span></div></td> </tr> </table> <!-- #EndLibraryItem --> <div align="center"></div></td> </tr> </table> </body> </html>
