Abstract
The synthesis, characterization and thermal behaviour of 12 dinuclear, orthopalladated complexes derived from Schiff's bases are reported. The complexes are of the type [Pd2(H-X)2C6H3(OR)–C(Z) = N-C6H4 R' 2] (X = OAc, Cl, Br, SCN; Z = H, CH3; R' = OR, R; R = C10H21) and ten of them exhibit ordered mesophases (SC and SA). The molecules were characterized structurally by I.R. and 1H N.M.R. spectroscopy in order to elucidate the possible existence of isomers. The connection between their molecular structures and their mesogenic properties is discussed.Keywords
