Synthesis and characterization of niobium(V) complexes of furoic acid hydrazones

83-86The metal complexes of niobium(V) with furoic acid hydrazones have been synthesized in dry chloroform under nitrogen atmosphere and characterized by elemental analysis, molar conductance, electronic infrared. 1H NMR and thermal studies. It is proposed that the complexes exhibit coordination number seven

Synthesis and characterization of uranium(IV) complexes with 3-substituted-4- amino-5-mercapto-1 ,2,4-triazole Schiff bases

1087-1089The metal complexes of uranium(IV) with Schiff bases derived from 3-substituted-4-amino-5-mercapto-1,2,4-triazole and glyoxal/biacetyl/benzil have been synthesized in dry benzene under nitrogen atmosphere. These complexes have been characterized by elemental analyses, molar conductance, electronic, infrared and thermal studies. On the basis of these observations it is suggested that uranium(IV) complexes exhibit coordination number six
