Abstract :The reactions of dioxouraniuminsert ignore into journalissuearticles values(VI); acetate with several semicarbazones derived from 4-aminoantipyrine in the presence of diphenyl sulfoxide insert ignore into journalissuearticles values(DPSO); led to the formation of complexes corresponding to the formulae [UO2insert ignore into journalissuearticles values(CH3COO);2 insert ignore into journalissuearticles values(L);.DPSO], where L = 4[N-insert ignore into journalissuearticles values(benzalidene);amino]antipyrinesemicarbazone insert ignore into journalissuearticles values(BAAPS);, 4[N-insert ignore into journalissuearticles values(2`-hydroxybenzalidene);- amino]antipyrinesemicarbazone insert ignore into journalissuearticles values(HBAAPS); 4[N-insert ignore into journalissuearticles values(4`-methoxybenzalidene);amino] antipyrine semicarbazone insert ignore into journalissuearticles values(MBAAPS); 4[N-insert ignore into journalissuearticles values(4`-dimethylaminobenzalidene);amino]- antipyrinesemicarbazone insert ignore into journalissuearticles values(DABAAPS); 4[N-insert ignore into journalissuearticles values(2`-nitrobenzalidene);amino]antipyrine- semicarbazone insert ignore into journalissuearticles values(2`-NO2 BAAPS); 4[N-insert ignore into journalissuearticles values(3`-nitrobenzalidene);amino]antipyrine- semicarbazone insert ignore into journalissuearticles values(3`-NO2BAAPS); 4[N-insert ignore into journalissuearticles values(4`-nitrobenzalidene);amino]antipyrine- semicarbazone insert ignore into journalissuearticles values(4`-NO2BAAPS);, 4[N-insert ignore into journalissuearticles values(4`-hydroxy-3`-methoxybenzalidene);amino]- antipyrinesemicarbazone insert ignore into journalissuearticles values(HMBAAPS); 4[N-insert ignore into journalissuearticles values(2`-hydroxy-1`-naphthalidene);amino]- antipyrinesemicarbazone insert ignore into journalissuearticles values(HNAAPS); 4[N-insert ignore into journalissuearticles values(cinnamalidene);amino]antipyrine- semicarbazone insert ignore into journalissuearticles values(CAAPS);4[N-insert ignore into journalissuearticles values(3`,4`,5`-trimethoxybenzalidene);amino]antipyrine- semicarbazone insert ignore into journalissuearticles values(TMBAAPS); and 4[N-insert ignore into journalissuearticles values(furfural);amino]antipyrinesemicarbazone insert ignore into journalissuearticles values(FFAAPS);. The complexes were characterised by means of elemental analyses, conductivity measurements, molecular weight, magnetic moments and infrared studies. The coordination number 10 is proposed for these complexes. Thermal properties of the representative complexes are also reported.
