The asymmetric unit of the title compound, [Co(C(4)H(6)N(2))(6)]Br(2)·2H(2)O, contains one-half of the centrosymmetric cation, one Br atom and one water mol-ecule. The Co(II) atom, lying on an inversion center, has a distorted octa-hedral geometry, defined by six N atoms from six 1-methyl-imidazole ligands. In the crystal structure, intra- and inter-molecular O-H⋯Br hydrogen bonds link pairs of uncoordinated water mol-ecules and bromide anions.
标题化合物[Co(C₄H₆N₂)₆]Br₂·2H₂O的不对称单元包含一个中心对称阳离子的一半、一个Br原子和一个水分子。位于对称中心的Co(II)原子具有由六个1-甲基咪唑配体的六个N原子定义的扭曲八面体几何构型。在晶体结构中,分子内和分子间的O—H⋯Br氢键连接未配位的水分子和溴离子对。
