摘要：

Crystals of [Cr3O(CH3COO)(6)(H2O)(3)][UO2(CH3COO)(3)]center dot 3H(2)O (I) were synthesized for the first time and studied by X-ray crystallography. The crystals of I are orthorhombic: a = 8.3561(3) , b = 16.8421(5) , c = 25.7448(9) , V = 3623.2(2) (3), space group P2(1)2(1)2(1), Z = 4, R = 0.0409. The structure is composed of trinuclear [Cr3O(CH3COO)(6)(H2O)(3)](+) complexes and mononuclear [UO2(CH3COO)(3)](-) complexes classified with crystal-chemical groups A(3)M(3)B (6) (2) M (3) (1) (A = Cr3+, M-3 = O2-, B-2 = CH3COO-, M-1 = H2O) and AB (3) (01) (A = UO (2) (2+) , B-01 = CH3COO-), respectively. The complexes are bound to each other by electrostatic interactions and hydrogen bonds involving outer-sphere water molecules. The results of IR spectroscopic study of I are in good agreement with the structural data for the crystal.
