Modi, C. K. published the artcileSynthetic, spectroscopic and thermal aspects of some heterochelates, Recommanded Product: 5-Methyl-2-phenyl-4-(2,2,2-trifluoroacetyl)-1H-pyrazol-3(2H)-one, the main research area is transition metal pyrazolylethylideneaminobenzoate benzylideneethylenediamine preparation; reaction kinetics activation energy thermolysis transition metal pyrazolylethylideneaminobenzoate benzylideneethylenediamine; activation entropy enthalpy thermolysis transition metal pyrazolylethylideneaminobenzoate benzylideneethylenediamine; free energy thermolysis transition metal pyrazolylethylideneaminobenzoate benzylideneethylenediamine.

The present article describes the synthesis, structural features and thermal studies of heterochelates [M(SB)(benen)(H2O)]·nH2O [where H2SB = (Z)-2-(2,2,2-trifluoro-1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)ethylideneamino)benzoic acid, benen = bis(benzylidene)ethylenediamine and M = Mn(II), Co(II), Ni(II), Cu(II), Zn(II) and VO(IV)]. The Schiff base (H2SB) was characterized from elemental anal., IR, 1H and 13C NMR. The heterochelates were characterized from elemental analyses, magnetic measurements, solid state conductivity measurements, IR, reflectance spectra, and thermal studies. The FAB mass spectrum of [Co(SB)(benen)(H2O)] was carried out. The kinetic parameters such as order of reaction (n) and the energy of activation (Ea) are reported using Freeman-Carroll method. The pre-exponential factor (A), the activation entropy (ΔS#), the activation enthalpy (ΔH#) and the free energy of activation (ΔG#) were calculated
