Abstract: | Thermal studies have been carried out on NiL3]X2·n H2O, whereL=1,2-propanediamine;X=Cl–, Br–, SCN–, 1/2SO

; andn= 2, 1.5 and 0. Ni2L5(NCS)2](SCN)2 and NiL2SO4] have been synthesized pyrolytically in the solid-state from their mother diamine complexes. The deaquation behaviour of NiL3]SO4·2 H2O appears interesting, and its monohydrate undergoes a solid-state reaction (88–102°) without mass loss, showing an exothermic peak at 95 °C ( H=– 5.1 kJ mole–1).
Zusammenfassung Thermische Untersuchungen wurden an NiL3]X2,n H2O ausgeführt, wobeiL-1,2-Propandiamin;X=Cl–, Br–, SCN–, 1/2 SO

;n=2, 1.5 und 0. Ni2Ls(NCS)2](SCN)2 und NiL2SO4] wurden ausgehend von den entsprechenden Diaminkomplexen pyrolytisch im festen Zustand synthetisiert. Das Dehydratisierungsverhalten von NiL3]SO4·2 H2O scheint interessant zu sein, und beim entsprechenden Monohydrat wird eine ohne Massenverlust verlaufende Festkörperreaktion (88–102°) beobachtet, die sich durch einen exothermen Peak bei 95 °C ( H=– 5.1 kJ mol–1) zu erkennen gibt.
