A novel 1D coordination chain polymer {[Cu-2(pydc)(2)(1,10-phen)(H2O)(2)]center dot 3H(2)O}(n) (pydc = pyridine-2,3-dicarboxylate, 1,10-phen = 1,10-phenantroline) has been synthesised and characterised by elemental analysis, FT-IR spectrum, thermal analysis and variable temperature magnetic susceptibility studies. Single crystal X-ray diffraction measurement of the complex shows two Cu(II) centres are in distorted square pyramidal geometry. The complex shows very interesting hydrogen bonding modes involving the lattice and coordinated water Molecules with dicarboxylates. Low temperature magnetic susceptibility studies reveal a weak antiferromagnetic Coupling interaction of J = -5.71 cm(-1).
