Abstract 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, 2 J = 1.52 cm –1 . A comparison for the magnetic coupling of [CuLCl] 2 with other reported Cu(μ‐Cl) 2 Cu 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)
