Popis:	The synthesis and characterization of the μ-Cl-bridged dinuclear complex [CuLCl]2 with the new Schiff-base ligand HL, 2-methyl-6-[(pyridine-2-ylmethylene)amino]phenol, is reported. The structural study shows the complex has the unusual distorted trigonal-bipyramidal geometry. Variable temperature susceptibility measurements in the range of 2.0–300 K reveal a novel ferromagnetic coupling, 2J = 1.52 cm–1. A comparison for the magnetic coupling of [CuLCl]2 with other reported Cu(μ-Cl)2Cu compounds with square-pyramidal or trigonal-bipyramidal geometry is discussed in detail. The complex may provide useful information for the magneto-structural correlations of these compounds. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
