A new route to {Cu21-pyNH2)2(μ-OMe)2Cl2}n (pyNH2 = 2-aminopyridine) (3) is reported. Structural characterisation reveals the presence of methoxide and chloride bridging units within the complex which support close copper-copper bonding interactions resulting in interesting magnetic properties. The variable-temperature (4-300 K) magnetic susceptibility data of the complex were interpreted with the dimer law using the molecular field approximation. The results obtained indicate a weak antiferromagnetic (zJ′ = -15 cm-1) inter-chain interaction through the chloro-bridge. A relatively strong antiferromagnetic interaction, transmitted through the oxygen-bridge, with an exchange coupling of 2J = -305 cm-1, which dominates the magnetic properties of the title complex.
