<meta content="The complexes H2Ru3(CO)9C8H12, HRu3(CO)9C88H11, Ru4(CO)112C8H10, Ru4(C))12C8H10, and Ru4(CO)12C8H12 have been identified as the products of the reaction of alpha-H4Ru4(CO)12 with either cyclo-octa-1,5-diene or cyclo-octa-1,3-diene. The complexes are also formed by reaction of qlpha-H2Ru4(CO)13 with cyclo-octa-1,5-diene, and the complexes H2M3(CO)9C8H12 (M = Ru or 0s) are obtained by reaction of M3(CO)12 with cyclo-octene.  Structures of the complexes are discussed, where possible, in terms of spectroscopic data and in the case of Ru4(CO)11C8H10 on the basis of single crystal X-ray analysis. lH N.m.r. studies of H2Ru3(CO)9C8H12 indicate that the molecule undergoes two distinct types of fluxional behaviour involving in the first instance the C8H12 ligand, and in the second the two hydrido-ligands. DGact values for these processes (and for the corresponding osmium complex) have been determined. HRu3(CO)C8H11 reacts with hydrogen gas to give H2Ru3(CO)9C8H12.  The complexes Ru4(CO)llC8H10 and Ru4(CO)12C8H12 react with hydrogen to give H2Ru3(CO)9C8H12 and alpha-
H4RU4(CO)12, and Ru4(C0)12C8H10 forms alpha-H4Ru4(CO)12 only. aplpha-H4Ru4(CO)12 is converted into alpha-H2Ru4(CO)13 in ca. 30% yield by reaction with cycloheptene. The compounds Ru4(CO)12C8H10, Ru4(CO)12C8H12, HRu3(CO)9C8H11, and H2Ru3(CO)9C8H10 have been obtained from the reaction of Ru3(CO)12 with cyclo-octa-1,3-diene." name="eprints.abstract" />

The complexes are also formed by reaction of qlpha-H2Ru4(CO)13 with cyclo-octa-1,5-diene, and the complexes H2M3(CO)9C8H12 (M = Ru or 0s) are obtained by reaction of M3(CO)12 with cyclo-octene.  Structures of the complexes are discussed, where possible, in terms of spectroscopic data and in the case of Ru4(CO)11C8H10 on the basis of single crystal X-ray analysis. lH N.m.r. studies of H2Ru3(CO)9C8H12 indicate that the molecule undergoes two distinct types of fluxional behaviour involving in the first instance the C8H12 ligand, and in the second the two hydrido-ligands. DGact values for these processes (and for the corresponding osmium complex) have been determined. HRu3(CO)C8H11 reacts with hydrogen gas to give H2Ru3(CO)9C8H12.  The complexes Ru4(CO)llC8H10 and Ru4(CO)12C8H12 react with hydrogen to give H2Ru3(CO)9C8H12 and alpha-&#13;
H4RU4(CO)12, and Ru4(C0)12C8H10 forms alpha-H4Ru4(CO)12 only. aplpha-H4Ru4(CO)12 is converted into alpha-H2Ru4(CO)13 in ca. 30% yield by reaction with cycloheptene. The compounds Ru4(CO)12C8H10, Ru4(CO)12C8H12, HRu3(CO)9C8H11, and H2Ru3(CO)9C8H10 have been obtained from the reaction of Ru3(CO)12 with cyclo-octa-1,3-diene.</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 &gt; 259900 Other Chemical Sciences &gt; 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">2903</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">29 Jan 2008 10:26</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">29 Jan 2008 10:26</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=2903;">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&amp;eprintid=2903">item control page</a></p>
