Abstract
A dinuclear complex, [Cu2(μ-Cl)2Cl2(pbba)2] (1) [pbba=N-((pyridin-2-yl)benzylidene)benzylamine], has been isolated from the reaction of a 1:1M ratio of CuCl2·2H2O and pbba in MeOH solution at room temperature. Compound 1 has been characterized using microanalytical, spectroscopic, thermal and other physico-chemical results. Single crystal X-ray diffraction measurements show that each metal center in 1 adopts a distorted square pyramidal geometry with a CuN2Cl3 chromophore ligated through two N atoms of pbba and two bridging and one terminal chloride atom. The centrosymmetric dinuclear unit contains an asymmetric di-μ-chlorido bridge. Variable-temperature magnetic susceptibility measurements indicate weak intramolecular ferromagnetic coupling (J=+5.02±0.13cm−1) through chlorido bridges and weak intermolecular antiferromagnetic (J′=−0.32±0.01cm−1) interactions among the dinuclear entities, coupled with weak zero-field splitting arising from the S=1 ground state.
