The title complex, [Re(C(7)H(2)Br(3)O(2))(CO)(3)(H(2)O)]·CH(3)OH, crystallized as a neutral Re(I) compound and one methanol solvent mol-ecule in the asymmetric unit. The metal centre is coordinated facially by three carbonyl groups. The bidentate tribromo-tropolanate ligand and a water mol-ecule complete the distorted octahedral coordination around the central metal. Inter-molecular Br⋯O [3.226 (5) Å] and Br⋯Br [3.590 (2) Å] contacts are observed between adjacent mol-ecules. These contacts, together with an array of O-H⋯O, O-H⋯Br and C-H⋯O hydrogen bonds, complete a three-dimensional polymeric network formed between the methanol solvent and the complex.
标题配合物[Re(C₇H₂Br₃O₂)(CO)₃(H₂O)]·CH₃OH以中性铼(I)化合物和一个甲醇溶剂分子在不对称单元中结晶。金属中心由三个羰基以面式配位。双齿三溴环庚三烯酚酮酸配体和一个水分子完成了中心金属周围扭曲的八面体配位。在相邻分子之间观察到分子间Br⋯O [3.226 (5) Å]和Br⋯Br [3.590 (2) Å]接触。这些接触，连同一系列O-H⋯O、O-H⋯Br和C-H⋯O氢键，形成了甲醇溶剂与配合物之间的三维聚合物网络。
