Abstract
Complexes of lauric acid with general formula M(L)2 · xH2O (M = Cu, Co, Ni, Mn) and M(L)2 (M = Zn, Hg) where L = (CH3(CH2)10COOH) have been synthesized. Their elemental analyses show the good agreement between calculated and experimental values. These complexes have been characterized by spectroscopic techniques, such as IR, UV-visible, atomic absorption, and mass spectrometry, which show that the carboxylate group acts as bidentate in the solid state. Kinetic parameters, such as the order of reaction, activation energy, enthalpy, and entropy were calculated using the Coats and Horowitz methods. The calculated values are in a good agreement with the observed TG values that confirm the structural integrity of the complexes. These complexes were screened for their in vitro biological activities against different bacteria and fungi to establish their significance.
