  A new series of solvatochromic binuclear mixed ligand complexes with the general formula: Cu2(DMCHD)(Am)2X3 (where, DMCHD: 5.5-Dimethyl cyclohexanate 1,3-dione, Am=N,N,N’-trimethylethylenediamine (Me3en), N,N,N’,N’- tetramethylethylenediamine (Me4en), or N,N,N’,N’,N’’-penta-methyldiethylenetriamine (Me5dien) and X=ClO4- or Clhave been synthesized and characterized by the analytical, spectral methods, magnetic and molar conductance as well as electrochemical measurements. The formation constant values for HDMCHD ligand with various metal ions are much lower than expected for similar β-diketones revealing a monobasic unidentate nature of this ligand. The d-d absorption bands of the prepared complexes in weak donor solvents suggest square-planar, distorted octahedral and/ or distorted trigonal bipyramid geometrie.. View More»
