Six solid complexes of cobalt, copper, zinc and manganese with 2- amino-4, 6-dimethoxy-pyramidine (AMP) were prepared from AMP reacting with metal salts in absolute ethanol through reflux, concentration, cooling to room temperature and filtration. The composition of the complexes was determined by chemical and elemental analyses as Co(AMP) 2Cl2 (1), Cu(AMP)_2Cl_2 (2), Cu(AMP)_2(N0_3)_2 (3), Zn(AMP)_2Cl_2 (4), Mn(AMP)_2Cl_2 (5) and Zn(AMP)SO_4 (6) . The bonding characterization of the title complexes was investigated by IR and 'H NMR spectra. The constant-volume combustion heat of the ligand and the complexes (△_cU) was determined by a precision rotating bomb calorimeter at 298.15 K. Their standard molar combustion enthalpy (△_cH_m~θ) and standard molar enthalpy of formation (△_fH_m~θ) were calculated.
