| Abstract: | Solid complexes of M(His)2Cl2·nH2O (M=Mn, Co, Ni, Cu) of MnCl2·6H2O, CoCl2·6H2O, NiCl2·6H2O, CuCl2·2H2O and L-α-histidine (His) have been prepared in 95% ethanol solution and characterized by elemental analyses, chemical analyses,
IR and TG-DTG. The constant-volume combustion energies of the complexes have been determined by a rotating-bomb calorimeter.
And the standard enthalpies of formation of the complexes have been calculated as well.
