Synthesis, spectral, thermal and thermodynamic studies of oxovanadium(IV) complexes of Schiff bases derived from 3,4-diaminobenzoic acid with salicylaldehyde derivatives

Synthesis, characterization, and biological activities of oxovanadium(IV) and cadmium(II) complexes with reduced Schiff bases derived from N,Nʹ-o-phenylenebis(salicylideneimine)

“…2 The remaining part of the curves corresponds to the progressive degradation of the organic moiety, without marked steps. The final decomposition products obtained at 700 • C are the metal oxides VO 2 and CdO, respectively (Etcheverry et al, 2005;Mohammadi et al, 2013;Sahani et al, 2014), which was confirmed by comparing the observed and the calculated remaining mass. The cadmium complexes are slightly more stable than the oxovanadium ones with the final decomposition step occurring at ca 720 • C and 660 • C, respectively.…”

“…9). The band of higher energy may be attributed to p-p ⁄ intraligand transition, while the latter may be caused by the charge transfer phenomenon and its gradual disappearance is related to the decreasing concentration of free complexes in the solution due to incremental addition of CT-DNA [63].…”
