A cadmium-thiocyanate complex, poly[(1-cyanomethyl-4-aza-1-azoniabicyclo[2.2.2]octane-κ(4)N)octakis-μ2-thiocyanato-κ(8)N:S;κ(8)S:N-tricadmium(II)], [Cd3(C8H14N3)2(NCS)8]n, was synthesized by the reaction of 1-cyanomethyl-4-aza-1-azoniabicyclo[2.2.2]octane chloride, cadmium nitrate tetrahydrate and potassium thiocyanide in aqueous solution. In the crystal structure, there are two independent types of Cd(II) cation (one on a centre of inversion and one in a general position) and both are in distorted octahedral coordination environments, coordinated by N and S atoms from different ligands. Neighbouring Cd(II) cations are linked together by thiocyanate bridges to form a two-dimensional network. Hydrogen-bonding interactions are involved in the formation of a three-dimensional supramolecular network.
通过使1-氰基甲基-4-氮杂-1-氮鎓双环[2.2.2]辛烷氯化物、四水合硝酸镉和硫氰酸钾在水溶液中反应，合成了一种硫氰酸镉配合物聚[(1-氰基甲基-4-氮杂-1-氮鎓双环[2.2.2]辛烷-κ(4)N)八聚-μ2-硫氰酸根合-κ(8)N:S;κ(8)S:N-三镉(II)]，[Cd3(C8H14N3)2(NCS)8]n。在晶体结构中，存在两种独立类型的Cd(II)阳离子（一个位于对称中心，一个处于一般位置），且二者均处于扭曲的八面体配位环境中，由来自不同配体的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。氢键相互作用参与形成三维超分子网络。
