Synthesis of amidate-hanging platinum mononuclear complexes by base hydrolysis of nitrile complexes

Five novel “amidate-hanging” Pt mononuclear complexes, which can easily bind a second metal ion with the non-coordinated oxygen atoms in the amidate moieties, have been synthesized and characterized by 1H NMR, MS, IR spectroscopy, and single crystal X-ray analysis. Such complexes were prepared by direct base hydrolysis of the corresponding cis Pt nitrile complexes without geometry isomerization.
