Anal. data, 1H and 195Pt NMR spectroscopic as well as mass spectrometric results confirm the identity of the species. Cyclic voltammetry, EPR, and UV/Vis/NIR spectroelectrochem. were used to investigate the sequence of redn. steps and the location of the electron uptake. Redn. involves first the bpym ligand in two 2-electron waves and then the bp bridge in discernible one-electron steps. [on SciFinder(R)]
