SYNTHESIS AND CHARACTERIZATION OF DIOXURANIUM COMPLEXES WITH SCHIFF BASE AND SOLVENTS

Qiu Wang

Abstract

Four new complexes UO 2(Bsaladpp)LNO 3 and UO 2(Vanadpp)LNO 3 (BsaladppH=4 (5' bromosalicylideneimine) 2,3 dimethyl 1 phenyl 3 pyrazoline 5 one, VanadppH=4 (o vanillalimine) 2,3 dimethyl 1 pheny1 3 pyrazoline 5 one.) have been synthesized and characterized by elemental analysis, IR, UV,DTA TG and molar conductance. The possible structures of these complexes are proposed.
