| Abstract: A metal-organic coordination polymer framework formulated as {[Cu2(Imazameth)2(bipy)](ClO4)·CH2OH·H2O}n(1) (where Imazameth=(+/-)2-(4,5-Dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl)-5-methyl-3-pyridinecarboxylic acid, bipy=4,4′-bipyridine) has been prepared and characterized by spectral method (IR), elemental analysis, fluorescence properties and single crystal X-ray diffraction techniques. It crystallizes in the Monoclinic system, space group P21/c and the asymmetric unit contains hydrogen-bonded water and alcohol molecules. The Cu atom is five-coordinated by three N atoms and two O atoms in distorted pyramid coordination geometry. In fact, it is a new two-dimensional copper complex with the peculiarity of having the 4,4′-bipyridine ligand and Imazameth ligand acting as bridge to form “corrugated” layered structure . Intramolecular N-H…O and intermolecular O-H…O hydrogen bonds result in the formation of a supermolecular crystal, in which they seem to be effective in the stabilization of the structure. The complex displays strong fluorescence property. CCDC: 756106. | |
