MOLECULAR AND CRYSTAL STRUCTURE OF A MIXED-LIGAND CADMIUM COMPLEX WITH p-HYDROXYBENZOIC ACID AND MONOETHANOLAMINE

Single crystals of a mixed-ligand cadmium complex of the composition Cd(PHBA)(2)(MEA)(2) are grown from the solution of Cd(CH3OO)(2), p-hydroxybenzoic acid (PHBA) and monoethanolamine (MEA) in aqueous ethanol. The crystallographic data are as follows: a = 11.6400(2) angstrom, b = 10.1363(1) angstrom, c = 16.6296(2) angstrom, beta = 93.937(1)degrees, space group I2/a, V = 1957.44(5) angstrom(3), Z = 4. In the complex molecule located on the twofold axis, ligands of both types are bidentately bound to the cadmium ion having the coordination number 8. In the crystal structure, two H bonds of the O-H center dot center dot center dot O type combine complex molecules into layers parallel to the ab plane.
