چکیده

Apatite Pb 3 Bi 2 (GeO_4) was obtained by the solid-phase method from initial oxides of PbO, O and GeO sequential firing in air at temperatures 773-1003 K. Its crystal structure has been refined X-ray diffraction. The high-temperature heat capacity (350-1000 K) this compound measured differential scanning calorimetry. Based on these data, main thermodynamic functions are calculated. Keywords: apatite bismuth-lead germanate, synthesis, capacity, properties properties.

Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...
