Abstract

In the title polymeric complex, Co(NCS)(2){SC(NH(2))(2)}(2), the asymmetric unit comprises a Co(II) ion, which is situated on an inversion centre, an N-bound thio-cyanate anion and a μ(2)-bridging thio-urea mol-ecule. The Co(II) atom is coordinated in a distorted octa-hedral fashion within an N(2)S(4) donor set. The bridging thio-urea ligands link Co(II) ions into a polymeric chain extending along [100]. The mol-ecular conformation is stabilized by intra-molecular N-H⋯N hydrogen bonds, which generate S(6) ring motifs. The crystal packing is stabilized by N-H⋯S inter-actions, which connect the chains into a three-dimensional architecture.

摘要

在标题聚合物配合物Co(NCS)(2){SC(NH(2))(2)}(2)中，不对称单元包含一个位于对称中心的Co(II)离子、一个N配位的硫氰酸根阴离子和一个μ(2)-桥连硫脲分子。Co(II)原子在一个N(2)S(4)供体集合内以扭曲的八面体方式配位。桥连硫脲配体将Co(II)离子连接成沿[100]方向延伸的聚合物链。分子构象通过分子内N-H⋯N氢键得以稳定，这些氢键形成S(6)环模式。晶体堆积通过N-H⋯S相互作用得以稳定，这些相互作用将链连接成三维结构。
