摘要：
Crystal structures of CuInF5 7H(2)O and ZnGaF5 7H(2)O are determined. They are composed of centrosymmetric octahedral complex [Cu(1)(H2O)(6)](2+) and [Cu(2)(H2O)(6)](2+) ([Zn(1)(H2O)(6)](2+) and [Zn(2)(H2O)(6)](2+) respectively) cations and two types of centrosymmetric octahedral complex [In(1)F-4(H2O)(2)](-) and [In(2)F-6](3-) ([Ga(1)F-4(H2O)(2)](-) and [Ga(2)F-6](3-) respectively) anions. Coordinated H2O molecules in the complex [In(1)F-4(H2O)(2)](-) and [Ga(1)F-4(H2O)(2)](-) anions are in trans-positions. Branched systems of O-H...F and O-H...O hydrogen bonds organize the structural elements of the studied compounds into a three-dimensional framework. The unit cell parameters of some complex fluorides M(II)AF(5) 7H(2)O (M = Co, Ni, Cu, Cd; A = In, Ga) are determined by X-ray diffraction of polycrystals and two isostructural series are identified.
