Synthesis and spectral studies of thorium(IV) and dioxouranium(V) metal complexes with Schiff base ligand

A series of new complexes of Schiff base 2-bromo-1N-[4-N,N-bis(2'-cynoethylaminobenzalidene)]aminobenzene (BCABAB) have been prepared from thorium(IV) and dioxouranium(v) metal salts having composition UO 2 X 2 .nL (X = CH 3 COO - , NO - 3 , I - or NCS-, n = 2; X = ClO - 4 , n = 4; L = BCABAB) and ThX 4 .nL (X = NO - 3 , NCS - , n = 2, X = I - ; n = 4 and X = ClO - 4 ; n = 6, L = BCABAB). BCABAB acts as neutral monodentate ligand and coordinate to the metal ion via azomethine nitrogen.
