摘要

Chiral one-dimensional hydrogen bonded copper(II) complex [Cu(HL1)Cl]₂路H₂O (1) (HL1 = N-(2-hydroxyethyl)-5-nitrosalicylaldimine) has been synthesized and characterized by elemental analysis, crystal structure analysis and magnetic susceptibility. X-ray diffraction studies show that 1 is a binuclear copper(II) complex with a pair of chlorine atoms bridging the copper atoms in a central Cu₂Cl₂ core. Each copper(II) atom is five-coordinated in a square-pyramidal environment. Variable-temperature magnetic susceptibility measurements on the a binuclear complex 1 in the range 2-300 K indicate a weak antiferromagnetic coupling between the binuclear copper(II) centers, with J = 鈭?.274 cm^鈭? and the magneto-structural correlations are discussed in detail.
