Pseudo-tetrahedral copper(II) complexes containing 2,2′-biquinolyl

Abstract

The mono- and bis-2,2′-biquinolyl complexes Cu(biq)X 2 (X = Cl, Br, and NO 3) and Cu(biq) 2(ClO 4) 2 have been prepared. The electronic spectra of these compounds are consistent with a pseudo-tetrahedral arrangement about the copper atoms. The magnetic susceptibilities of these compounds over the temperature range ∼80-400°K obey a Curie-Weiss law with θ values in the range 0 to -7°K. The compounds' magnetic moments lie in the range 1.93-2.02 BM and this is comparable with the values of other known pseudo-tetrahedral copper(II) complexes. The brown bis complex readily absorbs water to form a green monohydrate, Cu(biq) 2(ClO 4) 2·H 2O. The possible structure of this compound is discussed.
