Abstract
The crystal structures of two cocrystallized complexes of MgCl2 with 2,4-pentanedione have been determined. The conglomerate crystallizes in the monoclinic system, space group P 2(1)/c (No. 14); a = 7.835(2), b = 18.169(4), c = 13.303(3) Angstrom, beta = 90.70(2)°, Z = 4. The former complex is a dimer which consists of two octahedra sharing one edge by two chlorine bridges between the metal atoms. The chelate ring in the equatorial plane and two apical water molecules realize the coordination polyhedron around each Mg atom. In the latter complex the metal lies at the center of a slightly distorted octahedron formed by six oxygens, four from two chelate ligands and two from apical water molecules.Pubblicazioni consigliate
