Poly[[bis[3-(1H-tetrazol-1-yl)propanoic acid-κN4]cadmium]-di-μ-thiocyanato-κ2N:S;κ2S:N]

Abstract

In the title compound, [Cd(NCS)2(C4H6N4O2)2]n, the CdII 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-tetrazol-1-yl)propanoic acid (Htzp) ligands in a distorted octahedral geometry. The SCN− anions bridge the CdII cations into a layer structure parallel to (100). A weak intramolecular C—H...N interaction occurs. The layers are further assembled into a three-dimensional supramolecular structure via classical O—H...O hydrogen bonds.
