A series of new complexes of Schiff base 2-bromo-1N[4-N,N-bis(2'-cynoethylaminobenzalidene)Jaminobenzene (BCABAB) have been prepared from thorium(IV) and dioxouranium(V) metal salts having composition UO₂X₂.nL (X = CH₃COO^-, NO^-3, I^- or NCS^-, n = 2; X = ClO^-4; L = BCABAB) and ThX₄.nL (X = NO^-₃, NCS^-, n = 2, X = I^- = 4 and X = ClO^-₄; n = 6, L = BCABAB). BCABAB acts as neutral monodentate ligand and coordinate to the metal ion via azomethine nitrogen.
