Abstract

The decomposition heats (ΔH) for complexes of the type Ni(NCS)2L2 were studied by means of a differential scanning calorimeter. From the decreasing values ofΔH the following order has been established:a) for pseudooctahedral complexes: py >β-pic > > Q; andb) for square-planar complexes: 2,6-lut > Q >α-pic. The results obtained are compared with the data from the TG, DTG, and DTA curves.

Résumé

Détermination par analyse enthalpique différentielle des chaleurs de décomposition (ΔH) des complexes de formule générale Ni(SCN)2L2. Le classement des valeurs deΔH par ordre décroissant montre que pour les complexes pseudo-octaédriques py >gb-pic > Q et que pour les complexes plans carrés lut-2,6 > Q >α-pic. Comparaison de ces résultats avec les données des courbes TG, TGD et ATD.

Zusammenfassung

Es erfolgte die Bestimmung der Zersetzungswärmen (ΔH) der Komplexe vom Typ Ni(NCS)2L2 durch die Differential Scanning Calorimetrie. Mit abnehmendenΔH Werten ergab sich die Reihenfolge:a) Pseudooktaedrische Komplexe: Py >ß-Pic > Q;b) Quadratische Komplexe: 2,6-Lut. > Q >α-Pic. Ergebnisse mit aus den DTA, TG und DTG-Kurven gewonnenen Resultaten wurden verglichen.

Резюме

С помощью сканирующе го калориметра изуче на теплота распада (ΔH) дл я комплексов типа Ni(NCS)2L2. В р яду уменьшающих вели чинΔH найден следующий пор ядок: а) для псевдооктаэдри ческих комплексов ру >β-pic > Q; и б) для планарных комплексов 2,6 lut > Q >α-Pic. Полу ченные результаты сравнены с данными, по лученными исходя из кривых ТГ, ДТ Г и ДТА.
