Abstract: A new series of binucleating tetradentate ligands, Sal-dadpmX, and complexes of the type M2(SaldadpmX)2 have been synthesised and characterised by elemental analysis, spectral, magnetic and thermal studies, where Sal-dadpmX refers to 3,3'-di(X)-substituted-4,4'-bis(salicylideneimino)diphenylmethane (X=H, CH3, OCH3, Cl) and M=Cu(II), Ni(II), Co(II) and dioxouranium(VI). The results indicate a binuclear structure for Cu(II) complexes with pseudo-tetrahedral geometry and polynuclear structures for Ni(II), Co(II) and dioxouranium(VI) complexes with near octahedral geometry. The two Cu(II) centres of Cu2(Sal-dadprnX)2 exhibit one step two-electron cyclic voltammetric responses due to Cu(II)/Cu(I) at ~ - 0.35V and Cu(II)/Cu(III) at ~ + 0.45V (vs SCE).
