Abstract: A few copper complexes with N,N'-(6-methyl-1,3,5-triazine-2,4-diyl)bis(3-oxobutanamide) (L1) and N,N'-(6-phenyl-1,3,5-triazine-2,4-diyl)bis(3-oxobutanamide) (L2) have been reported in this paper. The electronic, IR, 1H NMR, Powder X ray diffraction, ESR spectral data indicate that Cu(II) complexes show coordination number six with ligands (L1) and (L2) with involvement of one water molecule coordinated to Cu(II) metal ion and this was confirmed by means of the analysed Cu(II) complexes which were studied spectrally and thermally. For the spectrophotometric analysis of Cu(II), a novel form of compound called copper(II) complexes containing L1 as well as L2 has been produced at different temperatures i.e, 250C, 300C, 350C, 400C, 450C, and 500C,. The stability constants values were found to decline with increasing temperature. Gibb's free energy change (ΔG), change in entropy (ΔS), and change in enthalpy (ΔH) are thermodynamic variables were studied. It has been found that the formations of metal complexes are random and exothermic in nature.
