摘要
The crystal structure of [Cu(sal ala)bipy]·CH 3OH·2H 2O (sal ala: salicylaldehyde alaninato, bipy: 2,2′ bipyridine), a potential anticancer agent and tumor imaging agent, is determined at 123 K. The complex crystallizes in triclinic, space group P - 1. The cell dimensions are a =0 894 8(2) nm, b =0 973 1(2) nm, c =1 263 2(3) nm; α =78 06(3)°, β =78 02(3)°, γ =88 22(3)°; V =1 052 6(4) nm 3, M r=479 99, Z =2, ρ c=1 514 g·cm -3 . The total number of 4 313 independent reflections with I>2σ(I) are used for the structure determination. The final R is 0 075 8 and R w is 0 179.The central Cu 2+ ion is penta coordinated by tridentate Schiff base and bidentate bipy, resulting in a distorted square pyramid coordination polyhedron. Three kinds of hydrogen bonds are revealed.
