The asymmetric unit of the title compound, {[Cd(2)(NCS)(2)(SO(4))(C(6)H(17)N(3))(2)]·0.5CH(3)OH}(n), consists of two Cd(2+) cations, two thio-cyanate and one sulfate anion, two bis-(3-amino-prop-yl)amine co-ligands and one methanol molecule with half-occupancy. Each Cd(2+) cation is coordinated by four N atoms of one terminal N-bonded thio-cyanate anion and one bis-(3-amino-prop-yl)amine co-ligand, and by two O atoms of two symmetry-related sulfate anions, defining a slightly distorted octa-hedral coordination polyhedron. Each two Cd(2+) cations are connected into dimers, which are located on centres of inversion and which are further μ-1,1:3,3-bridged via the sulfate anions into polymeric zigzag chains along the a axis.
标题化合物{[Cd₂(NCS)₂(SO₄)(C₆H₁₇N₃)₂]·0.5CH₃OH}ₙ的不对称单元由两个Cd²⁺阳离子、两个硫氰酸根离子和一个硫酸根阴离子、两个双(3-氨基丙基)胺共配体以及一个占据率为一半的甲醇分子组成。每个Cd²⁺阳离子由一个末端N键合硫氰酸根阴离子的四个N原子和一个双(3-氨基丙基)胺共配体配位,以及两个对称相关硫酸根阴离子的两个O原子配位,形成一个略微扭曲的八面体配位多面体。每两个Cd²⁺阳离子连接成二聚体,这些二聚体位于对称中心,并通过硫酸根阴离子进一步以μ-1,1:3,3-桥连方式沿a轴形成聚合物之字形链。
