Platinum amides from platinum nitriles: x-ray crystal structures of the unbridged dinuclear compounds bis[bis(1-imino-1-hydroxy-2,2-dimethylpropane)dichloroplatinum(II)] and bis[bis(1-imino-1-hydroxy-2,2-dimethylpropane)(1-amino-1-oxo-2,2-dimethylpropane)dichloroplatinum(II)]

Mono- and bisnitrile platinum complexes, [PtCl 3 (NCR)] - and cis- and trans-[PtCl 2 (NCR) 2 ] (R=Bu', Me and Ph), hydrolyze to amidate amide and mixed amide-nitrile complexes. The amide ligands generally adopt the enol tautomeric form and coordinate to platinum through nitrogen. The presence of two amides cis to one another plays a critical role in favoring the association of platinum units in dimers. For example, molecules of cis-[PtCl 2 (HN=C-(OH)Bu t } 2 ] 2 , 7b, comprise two monomeric units, placed face to face, with a Pt-Pt distance of 3.165(1) A and four interplanar N-H...Cl hydrogen bonds
