Ac. Gonzalez-baro et Ej. Baran, Synthesis and spectroscopic behavior of some oxovanadium(IV) and oxovanadium(V) complexes of 7-iodo-8-hydroxyquinoline-5-sulfonate, J BRAZ CHEM, 12(2), 2001, pp. 208-214
The oxovanadium (IV) complex [VOL2].5H(2)O (1) and the oxovanadium(V) compl
exes K[VOL2O].4H(2)O) (2), [VOL2OH] (3) and [VOL2OCH3] (4) (L = potassium s
alt of 7-iodo-8-hydroxyquinoline-5-sulfonic acid) were prepared and charact
erized. The IR spectra of the solids were recorded and discussed in compari
son with those of other similar compounds. The electronic absorption spectr
a, in different solvents, were also analyzed. Pre-resonance Raman measureme
nts, performed with the first two mentioned complexes, reinforce some of th
e spectroscopic assignments.
