Abstract
The solid phase thermal de-aquation of trans-[CrF(H2O)(tmd)2][M(CN)4] (M=Pd, Pt) (tmd = 1,3-diaminopropane) has been investigated by means of DSC and TG measurements. The enthalpy of reaction has been determined and the activation energy has been found by non-isothermal and isothermal kinetic studies. The values found for the activation energy are low and similar to those reported for the analogous compound trans-[CrF(H2O)-(tmd) 2][Ni(CN)4] (about 120 kJ mole-1) and permit the assignment of a de-aquationanation mechanism of the SN1 type, involving penta-coordinated activated species and elimination of water as Frenkel defects. © 1993.
