A bridging ligand compound [(bipy)(DCA)Cu (DCA) Cu(bipy))H 2O)]·3H 2O (bipy=2,2′ bipy^ridine, DCA=demethylcantharate) has been synthesized by copper chloride dihydrate, 2,2′ bipyridine and disodium demethylcantharate. The structure was characterized by elemental analysis, IR, UV spectra and conductance. The crystal structure was determined by X ray single crystal diffraction. The crystal having empirical formula Cu 2C 36 H 40 N 4 ~O 14 belongs to triclinic with space group P 1-, a =1 1251(2) nm, b =1 2707(3) nm, c =1 7345(4) nm, α =94 86(3) o, β =107 61(3) o, γ =112 50(3) o, V =2 1264(7) nm 3, μ =1 066 mm 1 , Z =2, D c =1 374 g/cm 3, F (000)=908, R =0 0547, wR 2=0 1355, GOF =0 815, in which the copper atoms are six coordinated in a stretched aberration octahedral geometry. The compound was tested in vitro against human tumor cell lines, HL 60, BGC 823, Bel 7402 and Hela, and displayed high activity.
