Description

Solid solutions of M1/3Co2/3C2O4·2H2O (M=Fe, Ni, Zn, Cd) composition are synthesized. Isothermal diagrams of M1/3Co2/3C2O4·2H2O-N2H4-H2O (C2H5OH) systems are plotted. It is shown that in every of these systems two new hydrazine oxalate complexes with one or two hydrazine molecules are formed. Their roentgenograms, infrared spectra are obtained, pycnometric density is measured, structure is discussed

Abstract (Russian)

Синтезированы твердые растворы состава M1/3Co2/3C2O4·2H2O (M=Fe, Ni, Zn, Cd). Построены изотермические диаграммы систем M1/3Co2/3C2O4·2H2O-N2H4-H2O (C2H5OH). Показано, что в каждой из этих систем образуются два новых гидразиноксалатных комплекса с одной и двумя молекулами гидразина. Получены их рентгенограммы, ИК-спектры, измерена пикнометрическая плотность, обсуждено строение
