Abstract

The decompositions of the clathrate compounds [M(NCS)2(4-MePy)4]·nG (whereM=Mn, Co, Ni or Cd;G=4-methylpyridine (4-MePy), benzene or xylenes) were studied on a Q-derivatograph under quasi-equilibrium conditions and with linear heating. These clathrates can be divided into two groups, in which the loss of guest is either (I) accompanied by destruction of the host complex, or (II) occurs before decomposition of the host complex. Kinetic parameters were obtained.

Zusammenfassung

Die Zersetzung von Clathrat-Verbindungen der Zusammensetzung [M(NCS)2(4-MePy)4]·nG (M=Mn, Co, Ni, Cd;G=4-Methylpyridin (4-MePy), Benzen, o-,m, p-Xylen) wurde mittels Q-Derivatograph unter Quasi-Gleichgewichtsbedingungen und bei linearer Aufheizung untersucht.

Die studierten Clathrate lassen sich in zwei Gruppen einteilen, je nachdem ob die Abgabe des Gastmoleküls G entweder vor oder unter Gleichzeitiger Zerstörung des Wirtskomplexes erfolgt. Kinetische Parameter wurden ermittelt.

РЕЗЮМЕ

С помощью Q-дериватогр афа в квазиравновесн ых условиях и в условиях линейного нагрева изучено разл ожение клатратных со единений состава [M(NCS)2(4-MePy)2]·nG, гдеM дв ухвалентные марганец, кобальт, ник ель и кадмий, аG — 4-мбтил пиридин, бензол и ксилолы. Изученные клатраты м огут быть разделены п о тому признаку, что потеря м олекул внедрения сопровождается разл ожением комплекса ил и же процесс выделения таких моле кул происходит перед разложением ко мплекса. Установлены кинетические параме тры происходящих реа кций.
