Poly[dichloridobis[μ-1-(4-pyridylmethyl)-1,2,4-triazole]cadmium(II)]

Abstract

In the title coordination polymer, [CdCl2(C8H8N4)2]n, the CdII atom, lying on an inversion center, is coordinated by two Cl atoms and two triazole N atoms and two pyridyl N atoms from four 1-(4-pyridylmethyl)-1,2,4-triazole (pmta) ligands in a distorted trans-CdCl2N4 octahedral arrangement. The bridging pmta ligands, with a dihedral angle between the triazole and pyridyl rings of 71.86 (8)°, link the Cd atoms into a 44 sheet parallel to (overline{1}02). π–π interactions between the triazole rings [centroid–centroid distance = 3.428 (2) Å] connect the sheets.
