Poly[mu4-sulfido-tris(thiocyanato-kappaN)tris(mu3-1,2,4-triazolato-kappa(3)N(1):N(2):N(4))tetrazinc(II)]: a three-dimensional zinc sulfide coordination polymer.
The title compound, [Zn(4)(C(2)H(2)N(3))(3)(NCS)(3)S](n), is a three-dimensional coordination polymer consisting of tetrahedral SZn(4) clusters bridged by triazole ligands. In the tetrahedral unit, three Zn atoms are connected to six bridging triazolate ligands, whereas the fourth Zn atom (site symmetry 3m) is bonded to three terminal thiocyanate anions that protrude into the void space created by the Zn-triazolate network. The network prototype is simple cubic, but a strong distortion along a body diagonal and the imposition of a polar direction by the arrangement of the molecular constituents lead to the trigonal space group R3m. This study demonstrates the use of the 3-mercapto-1,2,4-triazole ligand as an effective source for sulfide ions in the synthesis of sulfide-based coordination polymers.
