Biochemically Relevant Complexes of Copper: Synthesis, Magnetic and Spectral Studies of Some Mixed-Ligand Chelates of Bis(O-Hydroxyacetophenonato)Copper(II) with Benzothiazole and Related Ligands

Abstract

A series of novel mixed-ligand complexes of copper(II) of the compositions [Cu(o-haph)₂(L)₂], where o-haphH - o-hydroxp-acetophenone ard L - benzothiazole, 2-methylbenzothiazole, 2-(2′-hydroxyphenyl)benzothiazole, 2-(2′-tolyl)benzothiazole or 2-(3′-tolyl)benzothiazole, and [Cu(o-haph)₂(AMBZT)], where AMBZT = 2-aminobenzothiazole, have been prepared by the interaction of [Cu(o-haph)₂].H₂0 With the ligands. The compounds so obtained were characterized by analytical data, molar conductances, magnetic measurements, electron paramagnetic resonance and infrared spectrel studies. Suitable octahedral structures have been proposed for these complexes.
