The solid‐solid state reactions of o ‐aminobenzoic acid with Zn(OAc) 2 ·2H 2 O, Cu(OAc) 2 ·H 2 O, Ni(OAc) 2 ·4H 2 O and Mn(OAc) 2 ·4H 2 O result in the formation of corresponding complexes M(OAB) 2 (M = Zn(II), Cu(II), Ni(II), Mn(II)). XRD, IR and elemental analysis methods have been used to characterize the solid products. The activation energies of these reactions, which are calculated from the kinetic data obtained by means of the isothermal electrical conductivity measurement method, have been found to increase in the order: Cu(OAc) 2 ·H 2 O(37.7 kJ‐mol −1 )∼Mn(OAc) 2 ·4H 2 O (39.7 kJ·mol −1 ) < Zn(OAc) 2 ·2H 2 O (56.3 kJ·mol −1 ) < Ni(OAc) 2 ·4H 2 O (85.2 kJ·mol −1 ). The trend is related to their crystal structures.
