【 摘 要 】

The structures of two facially coordinated Group VII metal complexes are reported, namely: fac-bromido­[2-(2,2′-bipyridin-6-yl)benzoic acid-κ2N,N′]tricarbonyl­manganese(I) tetra­hydro­furan monosolvate, [MnBr(C17H12N2O2)(CO)3]·C4H8O, I, and fac-[2-(2,2′-bipyridin-6-yl)benzoic acid-κ2N,N′]tricarbonyl­chlorido­rhenium(I) tetra­hydro­furan monosolvate, [ReCl(C17H12N2O2)(CO)3]·C4H8O, II. In both complexes, the metal ion is coordinated by three carbonyl ligands, a halide ion, and a 2-(2,2′-bipyridin-6-yl)benzoic acid ligand, in a distorted octa­hedral geometry. In manganese complex I, the tetra­hydro­furan (THF) solvent mol­ecule could not be refined due to disorder. The benzoic acid fragment is also disordered over two positions, such that the carb­oxy­lic acid group is either positioned near to the bromide ligand or to the axial carbonyl ligand. In the crystal of I, the complex mol­ecules are linked by a pair of C—H⋯Br hydrogen bonds, forming inversion dimers that stack up the a-axis direction. In the rhenium complex II, there is hydrogen bonding between the benzoic acid moiety and a disordered co-crystallized THF mol­ecule. In the crystal, the mol­ecules are linked by C—H⋯Cl hydrogen bonds, forming layers parallel to (100) separated by layers of THF solvent mol­ecules.
