The potentiostatic reduction of cis-PtCl2(RNC)2 (3a: R = 2,4-t-Bu2-6-MeC6H2; 3b: R = 2,4,6-t-Bu3C6H2; 3c: R = 2,6-Me2C6H3) were carried out on a mercury pool electrode in CH3CN.The one-electron reduction (96.5 kC/mol) of 3a and 3b gave 2 (4a and 4b).An X-ray analysis of 4a showed that the two PtCl(RNC)2 planes jointed by a Pt-Pt bond were perpendicular.The two-electron reductions (2x96.5 kC/mol) of 3a and 3b gave Hg2 and Pt3(RNC)6, respectively.Electrolysis of 3c gave only Hg2.
