The asymmetric unit of the title compound, Cd(NCS)(2)(C(5)H(5)N)(2), consists of two crystallographically independent Cd(II) cations, four thio-cyanato anions and four pyridine ligands. The Cd(II) atoms are each coordinated by four N atoms from two pyridine ligands and two thio-cyanato anions, each in a mutually cis orientation, and by two S atoms from two adjacent thio-cyanato anions within a slightly distorted octa-hedral coordination environment. The Cd(II) atoms are μ-1,3-bridged via the thio-cyanato anions into polymeric chains parallel to [001]. The Cd(II)⋯Cd(II) intra-chain separations range between 5.9688 (6) and 6.0195 (6) Å, whereas the shortest Cd(II)⋯Cd(II) inter-chain separations are 7.8272 (7) and 8.6312 (6) Å.
标题化合物Cd(NCS)(2)(C(5)H(5)N)(2)的不对称单元由两个晶体学独立的Cd(II)阳离子、四个硫氰酸根阴离子和四个吡啶配体组成。每个Cd(II)原子由来自两个吡啶配体的四个N原子和两个硫氰酸根阴离子配位，每个配体相互呈顺式取向，并且由来自两个相邻硫氰酸根阴离子的两个S原子在略微扭曲的八面体配位环境中配位。Cd(II)原子通过硫氰酸根阴离子以μ-1,3-桥连的方式形成平行于[001]的聚合物链。链内Cd(II)⋯Cd(II)间距在5.9688 (6)和6.0195 (6) Å之间，而最短的链间Cd(II)⋯Cd(II)间距为7.8272 (7)和8.6312 (6) Å。
