Four mixed-chelate copper (II) complexes containing acetylacetonate ion and various diimine ligand were prepared and characterized by elemental analysis, spectroscopic and molar conductance measurements. These complexes are fairly soluble in various solvents and show positive solvatochromism.

The syntheses, structures and spectroscopic properties of tricarbonylrhenium(I) complexes with N,N'bis(2-bromo, 4-bromo, 4-chloro and 3-methoxybenzaldehyde)-1,2-diiminoethane Schiff base ligands have been investigated in this paper. Characterization of these complexes was carried out with FTIR, NMR, UV-Vis spectroscopy, elemental analysis and X-ray crystallography. The electrochemical behavior of the investigated complexes has been studied by cyclic voltammetry. The crystal structures of the 4-chloro, 4-bromo and 4-methoxy substituted complexes are stabilized by intermolecular C-H center dot center dot center dot Cl and C-H center dot center dot center dot O hydrogen bonds. The remarkable features of the 2-bromo, 4-bromo and 4-chloro substituted complexes are short intermolecular halogen-oxygen contacts. In the 4-bromo complex, short intermolecular Br center dot center dot center dot O and O center dot center dot O contacts link neighboring molecules along the 11 001 direction, which are further stabilized by short intermolecular pi center dot center dot center dot pi interactions. In 2-bromo complex, intermolecular Br center dot center dot O interactions link neighboring molecules into 1D extended chains along the 101 01 and 10 0 11 directions, forming a 20 network which is parallel to the bc-plane.
