Abstract

One of the isomers of the ligand Me6[14]ane, ‘tet-b’ upon reflux with acrylonitrile produced N-pendent derivative ‘tet-bx’ in which two cyano-ethyl groups were attached on less crowded two trans-N atoms. The reaction of copper(II) perchlorate hexahydrate with ‘tet-bx’ yielded six coordinated octahedral reddish-purple [Cu(tet-bx)(ClO4)2]. The axial substitution reactions of [Cu(tet-bx)(ClO4)2] with KX (X= SCN, NO3, Cl, Br or I) and NaNO2 afforded six coordinated blue [Cu(tet-bx)(NCS)(ClO4)] and [Cu(tet-bx)(NO2)(H2O)]ClO4; red [Cu(tet-bx)(NO3)(H2O)]ClO4 and [Cu(tet-bx)Cl(H2O)]ClO4 and purple [Cu(tet-bx)Br(H2O)]ClO4 and [Cu(tet-bx)I(H2O)]ClO4. The complexes were characterized on the basis of elemental, spectroscopic, magnetochemical and conductometric analysis. The antibacterial activities of the concerned ligand and its copper(II) complexes have been tested against four selected bacteria.
