Abstract
Dentate ligands 2-[(2,3-dimethylphenyl)amino]benzoic acid (Mefenamic acid ) and 2,5-diamino-5-oxopentanoic acid(glutamine) were used as bidentate Lewis base to prepare solid complexes with Molybdenum (V), Tungsten (V)) and Lanthanum(III). The Photo degradation study was achieved for the complexes solutions in methanol. The prepared complexes were characterized by using spectroscopy methods like FTIR, UV-visible, Melting points and flame atomic absorption spectroscopy were calculated for all complexes. Furthermore the molar conductance of 0.001 M solutions in acetonitrile and magnetic susceptibility were performed to elucidate the proposed geometry and structures of prepared complexes. Magnetic susceptibility displayed that complexes had not diamagnetic properties. Photo kinetic study was done for La and Mo Complexes to study the photo sensitivity of prepared complexes. Half time of the complexes` photo reaction were achieved and order of reactions were calculated which appear that photo reaction of LaIII complex was from the first order and constant of reaction was calculated (1.62x10-2) min-1 and half time of reaction was (62.112) min. Also, order reaction of Mo (III) complex was from first order too, the value of constant of reaction was (1.88 min-1) and half time of reaction was (26.6) min. TGA analysis of MoIII was done.
