One complex [Cd(4,4′-bipy)(2,4-Cl 2C 6H 5OCH 2COOH) 2] n has been synthesized by means of solvent method with 2,4-dichiorphenowyacetic acid and 4,4′-bipyridine(4,4′-bipy). It crystallizes in the Monoclinic space group C2/cn, with a=2.3425(3) nm, 6=1.181 00(1.5) nm, c=0.97794(13) nm, β=96.819(2)°, V=2.6863(6) nm 3, D c=1.752 g · cm -3, Z=4, F(000)=I 408. Final GooF =1.038, R 1 =0.023 8, wR 2 = 0.060 4. The crystal structure shows that the cadmium ion is coordinated with four oxygen atoms from four 2,4-dichlorphenoxyacetic acid radical and ...
