摘要: Structural features of 26 mononuclear octahedral monooxo d2-Re(V) complexes with singly charged oxygen atoms bidentate-chelating (O,N) ligands (Ln), namely, [ReO(Ln)(Lmono)3] (where Lmono stands for a monodentate ligand) containing six- and seven-membered chelate rings ReNC3O ReNC4O, are considered. The O(Ln), one exception, in the trans positions to O(oxo). In [ReO(OPPh3)Cl2(L35)], position oxo ligand is occupied by neutral atom OPPh3. [ReO(Hal)2(Ln)(Lmono)] [(Lmono = PPh3, AsPPh3, OPPh3)] structures, two geometric isomers exist: halide either cis- or each other.
