Abstract

3-Formylsalicylic acid oxime (H3L) formed the following dinuclear CuII and NiII complexes:[Cu2 (HL) 2]· 0.5 H2O (1), Na [Cu2 (HL)(L)]· 3H2O (2) and [Ni2 (HL) 2]· 2.5 H2O (3). The structures of Na [Cu2 (HL)(L)(H2O)](2′) and [Ni2 (HL) 2 (H2O) 4]· 8H2O (3′) have been determined by X-ray crystallography. Complex 2 has a cis arrangement of the two ligands providing dissimilar {CuN2O2} and {CuO4} chromophores sharing the two ...
