Determination more accurate definition of crystal structure of ZnInF5x7H2O and CdGaF5x7H2O

The atomic structure of crystals of ZnInF5x7H2O has been established and the crystal structure of CdGaF5x7H2O adjusted on the basis of three-dimensional X-ray diffractometry data obtained at room temperature. The H atoms are localized on the difference synthesis of the electron density. The adjustment is accomplished by the least squares method with an allowance for the anisotropy of thermal vibrations of the atoms and the effect of secondary extinction and anomalous scattering to divergence factors of 1.6 and 2.4%, respectively. The peculiarities of the atomic structure of these compounds and the hydrogen bonds in them are discussed
