PIPERAZINE MONO- AND BIS- (DITHIOCARBAMATO) COMPLEXES OF OXOVANADIUM (IV): SYNTHESIS, CHARACTERIZATION AND alpha-AMYLASE INHIBITION STUDIES

Mono and bis (piperazine) dithiocarbamatocomplexes with oxovanadium(IV) have been synthesized. Structures of the complexes were proposed on the basis of elemental analysis, electricalconductance and spectral data (FTIR, UV-Vis., EPR, XRD). The mononuclear complex is non-electrolytic whiledinuclear complex is electrolytic in nature. The particle sizes of the complexes are found to be in 24-32 nm range using Debye-Scherrer formula. Antidiabeticproperties by alpha amylase inhibition activities of the complexes have also been determined.
