Abstract Some of the stable chelate complexes of uranium(VI) were prepared with alkyl or aryl (R) bridged o,o′-dihydroxyaryl Schiffbases of HOC6H4CHNRNCHC6H4OH and HOC10H6CHNRNCHC10H6OH (R: (CH2)n; (C2H4NH)n(C2H4); (C6H4CH2C6H4; o, m, p-C6H4). Their structures were determined by UV, IR and elemental analyses. It is evident that strong ligand-ion interaction usually caused the polymeric

Solvated oxovanadium(IV) complexes of Schiff bases derived from aromatic diamines and 2-hydroxy-1-naphthaldehyde have been prepared from ethanolic medium. The elemental analyses reveal that the complexes have the ratio 1:1, 2:2 and 1:2 (ligand:metal) composition which are nonelectrolyte in DMF. The coordination number six (octahedral geometry) is proposed for the complexes prepared. This is based on the results of IR, electronic and EPR spectra. TGA as well as DTA studies and the electrical properties and (I-V) characteristics for the metal complexes were investigated.
