Thermal behavior of complexes of general formula (n-CnH2n+1NH2)2CuCl2

The thermal behaviour and some relationships between the physical properties and structure of complexes of general formula (n-C_nH_2n+1NH₂)₂CuCl₂, with n = 10, 12, ? 18, have been investigated by DSC and X-ray powder diffraction techniques. The high enthalpy solid—solid phase transitions observed for the complexes in the temperature range 350–390 K could be associated with the disordering of the hydrocarbon regions of the structure, as already observed for other similar layer compounds.
