Perrhenate ligand as an analog of the methoxide group in alkoxide complexes. Synthesis and X-ray single crystal study of Ta2(OMe)8(ReO4)2

The interaction of Ta2(OMe)10 with Re2O7 in toluene in 1:2 ratio provided an approach to a new bimetallic complex, Ta2(OMe)8(ReO4)2(I), which in its solid state structure and solution behavior displayed a close analogy to the homometallic M2(OMe)10, M=Nb, Ta, and to M2O2(OMe)8, M=Mo, W, complexes.
