CRYSTAL STRUCTURE OF NITRATE tris(4-ALLYLTHIOSEMICARBAZIDE)- CHROMIUM(III) HYDRATE

Abstract

The crystal structure of nitrate tris(4-allylthiosemicarbazide)chromium(III) hydrate [CrL3](NO3)3(H2O)1.05 (I), where L is 4-allylthiosemicarbazide, is determined. The asymmetric unit of the cell of the crystal structure of I contains a complex of a chromium ion with three bidentate coordinated molecules L. The outer coordination sphere of the central atom contains a disordered water molecule and three nitrate ions. The coordination polyhedron of the chromium atom in complex I is an octahedron. In the crystal, the complexes of the compound under study are joined with each other by the outer-sphere nitrato groups into a three-dimensional branched net of hydrogen bonds.
