- Abstract
The structures of two facially coordinated Group VII metal complexes are reported, namely: fac -bromido-[2-(2,2'-bipyridin-6-yl)benzoic acid-κ
2 N , N ']tricarbonyl-manganese(I) tetra-hydro-furan monosolvate, [MnBr(C17 H12 N2 O2 )(CO)3 ]·C4 H8 O, I , and fac -[2-(2,2'-bipyridin-6-yl)benzoic acid-κ2 N , N ']tricarbonyl-chlorido-rhenium(I) tetra-hydro-furan monosolvate, [ReCl(C17 H12 N2 O2 )(CO)3 ]·C4 H8 O, 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 octa-hedral geometry. In manganese complex I , the tetra-hydro-furan (THF) solvent mol-ecule could not be refined due to disorder. The benzoic acid fragment is also disordered over two positions, such that the carb-oxy-lic acid group is either positioned near to the bromide ligand or to the axial carbonyl ligand. In the crystal of I , the complex mol-ecules 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 mol-ecule. In the crystal, the mol-ecules are linked by C-H⋯Cl hydrogen bonds, forming layers parallel to (100) separated by layers of THF solvent mol-ecules.- Published
