Abstract
The pyrolysis of hydrated bis(pyrazinecarboxylate)copper(II) under an argon atmosphere proceeds via the loss of the water molecules at 84–95°C, ΔH=40.4 kJ (mol H2O)−1 followed by the thermal decomposition of the complex at 284–325°C, ΔH=97.0 kJ·mol−1, yielding 0.72 mole of pyrazine, 0.28 mole of bipyrazine, and 2 mole of CO2 per mole of complex.
Zusammenfassung
Die Pyrolyse von hydratiertem Bis-(pyrazincarboxylat)kupfer(II) in einer Argonatmosphäre verläuft über den Verlust der Wassermoleküle bei 84–95°C, ΔH=40.4 kJ/mol H2, gefolgt von einer thermischen Zersetzung des Komplexes bei 284–325°C, ΔH=97.0 kJ/mol, wobei man je 1 mol Komplex 0.72 mol Pyrazin, 0.28 mol Bipyrazin und 2 mol CO2 erhält.
