Abstract

In the title compound, [Ni(C3H10N2)3]2[Ni(C3H10N2)2(H2O)2]Br6·2H2O, one Ni(2+) cation, located on an inversion centre, is coordinated by four N atoms from two ligands and by two water O atoms. The other Ni(2+) cation, located in a general position, is coordinated by six N atoms from three ligands. In both cases, the Ni(2+) cation has an octa-hedral coordination environment. The overall structural cohesion is ensured by three types of hydrogen bonds, N-H⋯Br, O-H⋯Br and O-H⋯O, which connect the two types of complex cations, the bromide counter-anions and the lattice water molecules into a three-dimensional network.

摘要

在标题化合物[Ni(C₃H₁₀N₂)₃]₂[Ni(C₃H₁₀N₂)₂(H₂O)₂]Br₆·2H₂O中，一个位于对称中心的Ni²⁺阳离子由来自两个配体的四个N原子和两个水分子的O原子配位。另一个位于一般位置的Ni²⁺阳离子由来自三个配体的六个N原子配位。在这两种情况下，Ni²⁺阳离子都具有八面体配位环境。通过三种氢键N-H⋯Br、O-H⋯Br和O-H⋯O确保了整体结构的凝聚，这些氢键将两种类型的络合阳离子、溴化物抗衡阴离子和晶格水分子连接成三维网络。
