<meta content="Di-2-pyridyl ketone (dpk) reacts with dimethylgold(III) nitrate in water to form the complex [AuMe2(dpk.H2O)]NO3 in which the ligand has been hydrated to form a geminal diol. The closely related ketones 2-pyridyl-N-methyl-2-imidazolyl ketone (pik) and di(N-methyl-2-imidazolyl)
ketone (dik) react with Au(III)Me3 nitrate to form complexes that do not involve hydration of the ligand, [AuMe3(L)]NO3 (L = pik or dik). They react similarly with copper(II) sulphate and nickel(II) nitrate, forming [Cu(pik)(SO4)].0.5H2O, [Cu(dik)(SO4)].2H2O, [Ni(pik)(N03)2].0.5H2O and [Ni(dik)2(NO3)2].l.5Me0H; dpk forms [Ni(dpk.H2O)2(NO3)2].0.5H2O on reaction with nickel(II)
nitrate. The crystal structures of [AuMe2(dpk.H2O)]NO3 and [Cu(dik)(SO4)].2H2O have been determined by single-crystal X-ray diffraction at 295 K and refined by least-squares methods to R = 0.045 and 0.032 for 2 031 and 4 754 independent 'observed' reflections, respectively. The
cation [AuMe2(dpk.H2O)]+ has the ligand N,N-chelated with cis-square-planar co-ordination for gold(III), with an intramolecular hydroxy group positioned 2.850(8) A from the gold atom. The complex [Cu(dik)(SO4)].2H2O has square-pyramidal co-ordination for copper(II), with the
N,N-chelated ligand in the basal plane together with a water molecule and unidentate sulphate ion, and a water molecule co-ordinated axially. There is an intermolecular Cu...0 contact of 3.254(2) A with a ketone oxygen. Possible reasons for different behaviour of the ligands toward hydration are discussed." name="eprints.abstract" />

The closely related ketones 2-pyridyl-N-methyl-2-imidazolyl ketone (pik) and di(N-methyl-2-imidazolyl)
ketone (dik) react with Au(III)Me3 nitrate to form complexes that do not involve hydration of the ligand, [AuMe3(L)]NO3 (L = pik or dik). They react similarly with copper(II) sulphate and nickel(II) nitrate, forming [Cu(pik)(SO4)].0.5H2O, [Cu(dik)(SO4)].2H2O, [Ni(pik)(N03)2].0.5H2O and [Ni(dik)2(NO3)2].l.5Me0H; dpk forms [Ni(dpk.H2O)2(NO3)2].0.5H2O on reaction with nickel(II)
nitrate. The crystal structures of [AuMe2(dpk.H2O)]NO3 and [Cu(dik)(SO4)].2H2O have been determined by single-crystal X-ray diffraction at 295 K and refined by least-squares methods to R = 0.045 and 0.032 for 2 031 and 4 754 independent 'observed' reflections, respectively. The
cation [AuMe2(dpk.H2O)]+ has the ligand N,N-chelated with cis-square-planar co-ordination for gold(III), with an intramolecular hydroxy group positioned 2.850(8) A from the gold atom. The complex [Cu(dik)(SO4)].2H2O has square-pyramidal co-ordination for copper(II), with the
N,N-chelated ligand in the basal plane together with a water molecule and unidentate sulphate ion, and a water molecule co-ordinated axially. There is an intermolecular Cu...0 contact of 3.254(2) A with a ketone oxygen. Possible reasons for different behaviour of the ligands toward hydration are discussed.</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">ID Code:</th><td valign="top" class="ep_row">2831</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 08:47</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">14 Jan 2008 08:47</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=2831;">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=2831">item control page</a></p>
