Abstract

In the crystal structure of the title compound, Ni(2)(NCS)(4)(C(4)H(4)N(2))(3)(CH(3)OH)(2), each nickel(II) cation is coordinated by three N-bonded pyrimidine ligands, two N-bonded thio-cyanate anions and one O-bonded methanol mol-ecule in a distorted octa-hedral environment. The asymmetric unit consists of one nickel cation, two thio-cyanate anions and one methanol mol-ecule in general positions, as well as one pyrimidine ligand located around a twofold rotation axis. The crystal structure consists of μ-N:N' pyrimidine-bridged zigzag-like nickel thio-cyanate chains; these are further linked by μ-N:N-bridging pyrimidine ligands into layers which are stacked perpendicular to the b axis. The layers are connected via weak O-H⋯S hydrogen bonding.

摘要

在标题化合物[Ni₂(NCS)₄(C₄H₄N₂)₃(CH₃OH)₂]ₙ的晶体结构中,每个镍(II)阳离子在扭曲的八面体环境中由三个通过N键合的嘧啶配体、两个通过N键合的硫氰酸根阴离子和一个通过O键合的甲醇分子配位。不对称单元通常由一个镍阳离子、两个硫氰酸根阴离子和一个甲醇分子组成,以及一个位于二次旋转轴周围的嘧啶配体。晶体结构由μ-N:N'嘧啶桥连的锯齿状镍硫氰酸盐链组成;这些链通过μ-N:N桥连的嘧啶配体进一步连接成垂直于b轴堆叠的层。这些层通过弱O-H⋯S氢键相连。
