Description
| - A first organoplatinum(IV)-based molecular rectangle and bpyrn[{Pt(CH3)(3)}(4)(mu-eta(1):eta(1)-bp)(2)(mu-eta(2):eta(2)-bpym)(2)](4+) with bp = 4,4'-bipyridine and bpym = 2,2'-bipyrimidine has been obtained as tetrakis(triflate) in analogy to [{Re(CO)(3)}(4)(mu-eta(1):eta(1)-bp)(2)(mu-eta(2):eta(2)-bpym)(2)](4+), following the correspondence between the 5d(6) configured species [fac-Re-1(CO)(3)](+) and [fac-Pt-IV(CH3)(3)](+). 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.
