Dinuclear Cu(II) complexes bridged by 4,6-diacetylresorcinate (dar2-), [Cu2(dar)(bpy)2]X2 (X = ClO4- (1), BF4- (2)) and [Cu2(dar)(phen)2]X2 (X = ClO4- (3), BF4- (4)) have been prepared and studied in relation to their crystal structures and magnetic properties. The X-ray crystallography indicates that 1 and 2 have a 1-D network arrangement of the dar-bridged dinuclear units, combined by the `out-of-plane' bond through the phenolic oxygen, whereas 3 has a discrete dinuclear structure. Cryomagnetic studies indicate a weak antiferromagnetic interaction (J = -20 to approximately -9.9 cm-1) between Cu(II) ions through the dar bridge.
