摘要:
Complexes of zinc(II) with N,N'-disalicylidene-1,2-pheiiylenediamine (H(2)dsp), N,N'-disalicylidene-3,4-diaminotoluene (H(2)dst), 4-nitro-N,N'-disalicylidene-1,2-phenylenediamine (H(2)ndsp) and NAP-disalicylidene ethylenediamine (H(2)salen) have been prepared and characterized by elemental analysis, electronic, IR, H-1 NMR and thermal studies. TG studies show that all complexes decomposed in one step. Kinetic and thermodynamic parameters were computed from the thermal decomposition data. The activation energy of complexes lies 60-87 kJ mol(-1) range. (c) 2005 Elsevier B.V. All rights reserved.
