A cadmium-thiocyanate complex, poly[[bis(nicotinic acid-κN)di-μ-thiocyanato-κ(2)N:S;κ(2)S:N-cadmium(II)] monohydrate], {[Cd(NCS)2(C6H5NO2)2]·H2O}n, was synthesized by the reaction of nicotinic acid, cadmium nitrate tetrahydrate and potassium thiocyanide in aqueous solution. In the crystal structure, each Cd(II) cation is in a distorted octahedral coordination environment, coordinated by the N and S atoms of nicotinic acid and thiocyanate ligands. Neighbouring Cd(II) cations are linked together by thiocyanate bridges to form a two-dimensional network. Hydrogen-bond interactions between the uncoordinated solvent water molecules and the organic ligands result in the formation of the three-dimensional supramolecular network.
一种硫氰酸镉配合物,聚[[双(烟酸-κN)二-μ-硫氰酸根合-κ(2)N:S;κ(2)S:N-镉(II)]一水合物],{[Cd(NCS)₂(C₆H₅NO₂)₂]·H₂O}ₙ,通过烟酸、四水合硝酸镉和硫氰化钾在水溶液中的反应合成。在晶体结构中,每个Cd(II)阳离子处于扭曲的八面体配位环境中,由烟酸和硫氰酸根配体的N和S原子配位。相邻的Cd(II)阳离子通过硫氰酸根桥连在一起形成二维网络。未配位的溶剂水分子与有机配体之间的氢键相互作用导致形成三维超分子网络。
