Poly[[bis-[3-(1H-tetra-zol-1-yl)propanoic acid-κN(4)]cadmium]-di-μ-thio-cyanato-κ(2)N:S;κ(2)S:N].

In the title compound, Cd(NCS)(2)(C(4)H(6)N(4)O(2))(2), the Cd(II) cation is located on an inversion center and is coordinated by two N and two S atoms from four SCN(-) anions and two N atoms from two 3-(1H-tetra-zol-1-yl)propanoic acid (Htzp) ligands in a distorted octa-hedral geometry. The SCN(-) anions bridge the Cd(II) cations into a layer structure parallel to (100). A weak intra-molecular C-H⋯N inter-action occurs. The layers are further assembled into a three-dimensional supra-molecular structure via classical O-H⋯O hydrogen bonds.
