Five mixed-chelate copper(II) complexes with the general formula [Cu(acac)(diam)]ClO4, where acac is acetylacetonate ion and diam is N,N'-dibenzylic or thiophene derivatives of ethylenediamine were prepared and characterized by elemental analysis, spectroscopic and conductance measurements. The X-ray crystal analysis of these complexes demonstrated that ClO4- ions are bound weakly above and below of the chelate plane. In solution, the perchlorate ions are driven out by solvent molecules leading to their solvatochromism. (c) 2005 Elsevier B.V. All rights reserved.

Ethylenediamine was reacted with suitable aromatic aldehydes in order to prepare their respective diSchiff bases. These compounds were then reduced to give the corresponding tetrahydrodiSchiff bases, which were low melting in nature. Finally, these derivatives were condensed with different aromatic aldehydes to give the desired tetrahydroimidazoles. The structures of all these compounds were established on the basis of spectral data. These novel tetrahydroimidazoles showed promising anti-inflammatory and analgesic activity. The compounds were also screened for their anti-bacterial property against Staphylococcus aureus and Escherichia coli. (C) 2001 Editions scientifiques et medicales Elsevier SAS.
