The series of isostructural compounds [M(H2O)(6)][UO2(ac)(3)](2), where M = Mg2+ (1), Co2+ (2) and Zn2+ (3), ac = CH3COO-, has been prepared and characterized with single crystal X-ray diffraction and IR spectroscopy. Crystal structures of 1-3 are monoclinic, and contain isolated [M(H2O)(6))](2+) and [UO2(ac)(3)](-) complexes, whose mutual packing is led by electrostatic interactions and hydrogen bonds. In 3, hydrogen bonding of disordered aqua complex was studied using Voronoi-Dirichlet polyhedra (VDP). Characteristics of intermolecular interactions were calculated using molecular VDPs for complexes in 1, 2 and compared with those of previously reported [Be(H2O)(4)][UO2(ac)(3)](2).
