摘要:
A new cadmium coordination polymer, poly[bis(4-amino-4H-1,2,4-triazolium) [bis( 2-4-amino-4H-1,2,4-triazole-(KN1)-N-2:N-2)tetra-mu(2)-chlorido-tetrachloridotricadmium(II)] dihydrate], {(C2H5N4)2[Cd3Cl8(C2H4N4)(2)].2H2O}, 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 octahedral coordinations of CdIT 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 molecules form a network of hydrogen bonding. N - H center dot center dot center dot Cl and pi-pi stacking interactions are also involved in the supramolecular network stability.
