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)]ClO_4. 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.
