A first organoplatinum(IV)-based mol. rectangle Pt(CH3)34(m-h1:h1-bp)2(m-h2:h2-bpym)24+ with bp = 4,4'-bipyridine and bpym = 2,2'-bipyrimidine has been obtained as tetrakis(triflate) in analogy to Re(CO)34(m-h1:h1-bp)2(m-h2:h2-bpym)24+, following the correspondence between the 5d6 configured species fac-ReI(CO)3+ and fac-PtIV(CH3)3+. 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)
