Metal complexes of (LH2) ligand: 8,9-bis(hydroxyimino)-4,7,10,13-tetraaza-1,2,15,16-O-dicyclopentylidenehexadecane. Crystal structure, electrical andoptical properties

Molecular semiconducting complexes constitute one of the most fascinating, recent research topics, deeply involving both chemists and solid states phy sicists. Considerable interest has been shown in the synthesis and study of molecular complexes which may behave like semiconducting materials or at l east show high conductivities. In this study, structural, electrical and th ermal conductivity and optical properties of some inorganic complexes were investigated. From the XRD data, the unit cells of the samples were found a s L-Cu is amorphous and L-Ni, L-Co are orthorhombic. L-Cn, L-Ni and L-Co ha ve n-type of electrical conductivity. Electrical and optical band gaps of t he complexes were found to be 1.46-1.36, 2.68-2.71 and 1.40-1.32 eV, respec tively. (C) 2001 Elsevier Science B.V. All rights reserved.
