测定了2，4-戊二酮与氯化镁共结晶的两种配合物的晶体结构。该化合物属单斜晶系，空间群为P2(1)/c(14号)，a=7.835(2)，b=18.169(4)，c=13.303(3)，β=90.70(2)度，Z=4。赤道面上的螯合环和两个顶端的水分子实现了每个镁原子周围的配位多面体。在后者中，金属位于由六个氧形成的轻微扭曲的八面体的中心，其中四个来自两个螯合配体，两个来自顶端的水分子。
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)degrees, 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.
