<meta content="Reaction of palladium(II) acetate with l,3-bis[l - (pyridin-2-yl)ethyl] benzene and 1,3- bis(2-pyridinecarbonyl) benzene results in cyclopalladation and formation of 2,6-bis[l-(pyridin-2-yl)ethyl] phenyl and 2,6-bis(2-pyridinecarbonyl)phenyl complexes [Pd{(NC5H4CHMe)2C6H3}(O2CMe)].1.5H2O (1) and [Pd{(NC5H4CO)2C6H3}(O2CMe)] (4), respectively. X- Ray crystallographic studies reveal square-planar co-ordination and unidentate acetate groups, with tridentate [N-C-N]- intramolecular co-ordination involving two six-membered palladocycle rings.

X- Ray crystallographic studies reveal square-planar co-ordination and unidentate acetate groups, with tridentate [N-C-N]- intramolecular co-ordination involving two six-membered palladocycle rings. Proton n.m.r. spectra of complex (1) and its chloro-derivative
[Pd{(NC5H4CHMe)2C6H3}Cl] (2) indicate the presence of meso and rac diastereoisomers, but the crystal of (1) used for X-ray study contained the meso form only [monoclinic, space group C2/c with a = 26.08(1 ), b = 11.093(6), c = 15.846(7) A, beta = 116.19(3), and Z = 8; R = 0.042 for
2909 'observed' reflections]. Crystals of (4) contain two molecules in the asymmetric unit, with the molecules having different conformations of the tridentate ligand [monoclinic, space group Pc with a = 11.373(6), b = 10.925(6), c = 15.640(10) A, beta = 11 6.98(4), Z = 4; R = 0.043 (both chiralities) for 2677 'observed' reflections]. Syntheses of the new ligands are described.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><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">ID Code:</th><td valign="top" class="ep_row">2817</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">11 Jan 2008 08:50</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">11 Jan 2008 08:50</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=2817;">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=2817">item control page</a></p>
