A novel one-dimensional chain compound [Cu(dafo)(2) ( H2O)(2)] (OPA)(2) was synthesized. Its structure was determined by single-crystal X-ray diffraction. The crystal belongs to monoclinic system, P2 (1)/n space group. The crystallographic data are: a = 0.71093. ( 16) nm, b = 1.5724 (4) nm, c = 1.5357(3) nm, alpha = 90.000(5)degrees, beta = 102.220(4)degrees, gamma = 90.000 (5)degrees, V = 1.6778 (6) nm(3), Z = 2, F(000) = 814, M-r = 794.17, D-c = 1.527 g/cm(3), mu = 0.727 mm(-1), R-1 = 0.0406, wR(2) = 0.0930. The analysis of the crystal structure indicates that the compound has a one-dimensional chain structure, which is formed by hydrogen bonds.
