Abstract

A binuclear copper(II)—urea complex was synthesized and its structure was established from elemental analyses, IR, UV and visible spectroscopy and magnetic susceptibility measurements to be [OC(NH2)2Cu(OH)2]2. The kinetics of the thermal decomposition of the complex were studied by recording thermogravimetric measurements in streams of nitrogen and oxygen. TG analysis showed three main steps of decomposition, leading to Cu2O formation in the final stage.

Zusammenfassung

Der zweikernige Kupfer(II)-Harnstoff-Komplex wurde dargestellt. Durch Elementaranalyse, Spektroskopie im IR-, UV- und sichtbaren Bereich sowie Messung der magnetischen Suszeptibilität wurde die der Formel [OC(NO)2Cu(OH)2]2 entsprechende Struktur ermittelt. Die Kinetic der thermischen Zersetzung des Komplexes in Stickstoff und Sauerstoff wurde aus thermmogravimetrischen Kurven bestimmt, die drei Hauptzersetzungsttufen erkennen lassen. Endprodukt der thermischen Zersetzung ist Cu2O.

Резюме

Синтезирован двухяд ерный комплекс медь(Н) —мочевина и на основании элементного анализа, ИК спектроскопии, эле ктронных спектров поглощения и измерений магнитной восприимч ивости установлено, ч то состав его соответствует фо рмуле [OC(NH2)2·Cu(OH)2]2. Кинетика терми ческого разложения комплекса была изуче на путем термогравиметричес ких измерений в поток е азота и кислорода. Разложени е комплекса протекает в три стади и с образованием заки си меди в качестве конечного п родукта реакции.
