Abstract

In the title compound, the Co^II cations are octahedrally coordinated by two N-bonded thiocyanate anions, two 4-methylpyridine ligands and two water molecules into discrete complexes that are linked by O—H⋯S hydrogen bonds into layers. Upon heating, the title compound loses the water molecules and transforms into Co(NCS)₂(C₆H₇N)₂, which is already reported in the literature

The reaction of Co(NCS)₂ and 4-methylpyridine (C₆H₇N) in water leads to the formation of light-blue single crystals of the title compound, [Co(NCS)₂(C₆H₇N)₂(H₂O)₂]. The asymmetric unit consists of one Co^II cation (site symmetry 1) as well as one thiocyanate anion, one 4-methylpyridine coligand and one water molecule in general positions to generate trans-CoN₄O₂ octahedra. In the crystal, the complexes are linked by O—H⋯S hydrogen bonds into a layered network. Powder X-ray diffraction (PXRD) shows that a pure sample has been obtained. Upon heating, the title compound loses its water molecules and transforms into Co(NCS)₂(C₆H₇N)₂, which is already reported in the literature.

双水-双-（4-甲基吡啶-κ n）双-（硫氰基-κ n）钴（II）的合成、晶体结构和热性能

Co(NCS)2与4-甲基吡啶（C6H7N）在水中反应生成标题化合物[Co(NCS)2(C6H7N)2(H2O)2]的浅蓝色单晶。不对称单元由一个CoII阳离子（位对称1）、一个硫氰酸阴离子、一个4-甲基吡啶配体和一个在一般位置的水分子组成，生成反式con4o2八面体。在晶体中，配合物通过O-H⋯S氢键连接成层状网络。粉末x射线衍射（PXRD）表明得到了纯净的样品。加热后，标题化合物失去水分子，转化为Co(NCS)2(C6H7N)2，这在文献中已经有报道。
