A novel one-dimensional chain copper(II) coordination polymer {[Cu(2,2'-bipy)-(HPDA)](HPDA)(H2O)}(n) has been hydrothermally synthesized using pimelic acid, 2,2'-bipyridine and copper perchlorate in the mixture of water and methanol. The crystal structure was determined as a monoclinic system, space group P2(1)/c, with a = 1.01139(14), b = 2.6898(4), c = 1.02105(14), beta = 109.651(2)degrees, V = 2.6159(6) nm(3), D-c = 1.412 g/cm(3), Z = 2, F(000) = 1164, GOOF = 1.044, R = 0.0570 and wR = 0.1448. The copper ion is coordinated with two nitrogen atoms of one 2,2'-bipyridine molecule and three oxygen atoms from two heptane diacid molecules, forming a distorted square-pyramidal geometry. The result of TG analysis shows that the title complex is stable under 200.0 degrees C.
