Analytical data, H-1 and Pt-195 NMR spectroscopic as well as mass spectrometric results confirm the identity of the species. Cyclic voltammetry, EPR, and UV/Vis/NIR spectroelectrochemistry were used to investigate the sequence of reduction steps and the location of the electron uptake. Reduction involves first the bpym ligand in two 2-electron waves and then the bp bridge in discernible one-electron steps. Workplace J.
