A kinetic investigation was carried out by means of a thermomagnetic analysis on two structural transformation reactions in solid phase: monomeric square planar-to-polymeric octahedral for Ni(<I>N</I>-Me-salam)<SUB>2</SUB> and polymeric octahedral-to-monomeric square planar for Ni(<I>N</I>-Ph-salam)<SUB>2</SUB>. The polymerization process followed the Avrami-Erofeev equation (<I>n</I>=2) with <I>E</I><SUB>a</SUB>=303 kJ/mol and the monomerization followed the first order equation with <I>E</I><SUB>a</SUB>=78 kJ/mol. The thermal pyridine liberating reaction of Ni(<I>N</I>-Ph-salam)<SUB>2</SUB>py<SUB>2</SUB>, involving an octahedral-to-square planar transformation, has been investigated isothermally and found to follow the first order equation with <I>E</I><SUB>a</SUB>=167 kJ/mol.
