Abstract
Compounds having general formula: [M(4DMEAN)(x) (Cl)(2)(H2O)(gamma)]center dot ZH(2)O, where (M = Cu(II), Co(II), Ni(II) and Mn(II), 4DMEAN = 4-N,N-dimethyl-ethanolamine-N-allyl-1,8-naphthalimide, X = 1 or 2, Y = 0 or 2 and Z = 1, 2, 4 or 6) have been prepared. The resulted compounds were characterized by elemental analysis, conductivity measurements, magnetic measurements, (infrared, H-1 NMR, mass and electronic) spectra and thermogravimetric analysis. The results were suggested that all 4DMEAN complexes formed have a 1:1 M ratio (metal: 4DMEAN) except for Co(II) complex exist as 1:2. The 4DMEAN ligand acts as a neutral bidentate through both of the oxygen atom of (-C-OCH2) group and the lone pair of electron on the nitrogen atom of (N(CH3)(2) group. The molar conductance measurements proved that the 4DMEAN complexes are non-electrolytes. The kinetic thermodynamic parameters such as: E*, Delta H*, Delta S* and Delta G* were estimated from the DTG curves. (C) 2010 Elsevier B.V. All rights reserved.
