Aquatricarbonyl(3,5,7-tribromotropolonato)rhenium(I) methanol solvate

M. Schutte, H. G. Visser and A. Roodt

Abstract: The title complex, [Re(C₇H₂Br₃O₂)(CO)₃(H₂O)]·CH₃OH, crystallized as a neutral Re^I compound and one methanol solvent molecule in the asymmetric unit. The metal centre is coordinated facially by three carbonyl groups. The bidentate tribromotropolanate ligand and a water molecule complete the distorted octahedral coordination around the central metal. Intermolecular BrO [3.226 (5) Å] and BrBr [3.590 (2) Å] contacts are observed between adjacent molecules. These contacts, together with an array of O-HO, O-HBr and C-HO hydrogen bonds, complete a three-dimensional polymeric network formed between the methanol solvent and the complex.
