A series of five-coordinate copper(II) complexes with tripod ligands, tris(2-alkylthioethyl)amines (NS<SUB>3</SUB>–R, R=CH<SUB>3</SUB>, C<SUB>2</SUB>H<SUB>5</SUB>, <I>n</I>-C<SUB>3</SUB>H<SUB>7</SUB>, <I>i</I>-C<SUB>3</SUB>H<SUB>7</SUB>, and <I>t</I>-C<SUB>4</SUB>H<SUB>9</SUB>), [Cu(NS<SUB>3</SUB>–R)L](ClO<SUB>4</SUB>)<I><SUB>n</SUB></I>, where L represents Cl<SUP>−</SUP>, Br<SUP>−</SUP>, I<SUP>−</SUP>, NCS<SUP>−</SUP>, im(imidazole), py(pyridine) and H<SUB>2</SUB>O, <I>n</I>=1 or 2 were prepared and characterized. The electronic, infrared and ESR spectral data suggest that [Cu(NS<SUB>3</SUB>–Me)im](ClO<SUB>4</SUB>)<SUB>2</SUB> and [Cu(NS<SUB>3</SUB>–Me)OH<SUB>2</SUB>](ClO<SUB>4</SUB>)<SUB>2</SUB> have a five-coordinate square pyramidal geometry, the other complexes having distorted trigonal bipyramidal or trigonal bipyramidal geometry. The copper(I) complexes with NS<SUB>3</SUB>–Me, [Cu(NS<SUB>3</SUB>–Me)]ClO<SUB>4</SUB> and [Cu(NS<SUB>3</SUB>–Me)NCS] were also prepared and characterized.
