Abstract

Three complex compounds with the compositions Cu(NH3)3Ni(CN)4 (CuA), Zn(NH3)3Ni(CN)4 (ZnA), and Cd(NH3)3Ni(CN)4 (CdA) were prepared and identified. Their structures were examined by the methods of infrared spectroscopy and X-ray powder diffraction and compared with one another. The thermal stabilities and stoichiometries of thermal decomposition were investigated with a derivatograph. It follows from the results that the thermal stability increases in the sequence CuA < ZnA < CdA.

Zusammenfassung

Drei Komplexverbindungen der Zusammensetzung Cu(NH3)3Ni(CN)4 (CuA), Zn(NH3)3Ni(CN)4 (ZnA) und Cd(NH3)3Ni(CN)4 (CdA) wurden dargestellt und identifiziert. Die Strukturen der Verbindungen wurde infrarotspektroskopisch und röntgendiffraktometrisch untersucht und miteinander verglichen. Die thermische Stabilität und die Stöchiometrie der thermischen Zersetzung wurden mittels eines Derivatographen untersucht. Die thermische Stabilität nimmt in der Reihenfolge CuA < ZnA < CdA zu.

Резюме

Получены и идентифиц ированы три комплекс а состава Cu(NH3)3Ni(CN)4 (CuA), Zn(NH3)3Ni(CN)4 (ZnA) и Cd(NH3)3Ni(CN)4 (CdA). Структура комплексов была изучена методом ИК спектроск опии и порошковой рентгенографии, а пол ученные при этом данн ые сопоставлены друг с д ругом. С помощью дерив атографа исследована термоус тойчивость и стехиометрия термич еского разложения вс ех трех соединений. Установл ено, что термоустойчивость у величивается в ряду CuA<ZnA<CdA.
