A new Zn(Ⅱ) complex [Zn(Phen)_2(C_(12)H_6O_4N_2)(H_2O)]·3H_2O with 2,2'-bipyridine-3,3'-dicarboxylic acid and 1,10-phenanthroline (Phen) as ligands was synthesized, and the crystal data are as follows: monoclinic, space group P2_1/n, a = 12.5581(11), b = 17.3382(17), c = 15.6687(14) A,β= 110.579(2)°,M_r = 731.02,V = 3193.9(5) A~3, D_c = 1.520 g/cm~3, Z = 4, μ(MoKa) =0.833 mm~(-1), F(000) = 1508, the final R= 0.0431 and wR= 0.0936. In the title complex,the central Zn(Ⅱ) ion is located in a distorted octahedral coordination environment. The...
