Abstract
Fluoride amino acid complexes of vanadium(IV) of the type A[VOF2L(H2O)] (A = Naor NH4, L = cysteinate) and A[VOF3L(H2O)] (A = NH4 for L = alanine and A = Na, NH4 or K for L = serine) have been synthesised. The compounds have been characterised by chemical analyses, chemical determination of the oxidation state of vanadium, solution electrical conductance and magnetic susceptibility measurements, ESR, IR and electronic spectral studies. The vibrational spectra of the complexes indicate coordination of the amino acids through their carboxylate group to the metal centre. Also, the sulphydryl functionality provides an additional coordination site in cysteine-containing complexes. Fluoride appears to act as a stabilising ligand which helps in the solid-state isolation of the complexes.
