A new cadmium coordination polymer based on 4-amino-4H-1,2,4-triazole.

ABSTRACT: A new cadmium coordination polymer, poly[bis-(4-amino-4H-1,2,4-triazolium) [bis-(?2-4-amino-4H-1,2,4-triazole-?2N1:N2)tetra-?2-chlorido-tetra-chlorido-tri-cad-mium(II)] dihydrate], {(C2H5N4)2[Cd3Cl8(C2H4N4)2]·2H2O} n , was synthesized by the reaction of 4-amino-4H-1,2,4 triazole with cadmium(II) chloride in aqueous solution. With an unusual architecture, the crystal structure exhibits two distorted octa-hedral coordinations of CdII joined by edge sharing. The first is composed by four chlorine and two N atoms from the triazole ligands. The second is formed by five Cl atoms and by one N atom from the triazole ligand. The charge of the resulting two-dimensional anionic framework is balanced by the organic triazole cations. The lattice water mol-ecules form a network of hydrogen bonding. N-H?Cl and ?-? stacking inter-actions are also involved in the supra-molecular network stability.
