The complex [Zn(bipy) 3] 2·4Cl·5H 2O(bipy=2,2′ bipyridine) was synthesied and characterized by X ray diffraction. X ray diffraction result of the crystal showed that the crystal belongs to monoclinic, space group Cc, a =1.3610(2)(nm), b =2.2544(5)(nm), c =2.3775(4)(nm), β=105.77(1)(°),V =7.0200(2)(nm 3), F W=1299.92,Dc=1.220 g·cm -1 ,Z=4,μ=0.886 mm -1 ,F(000)=2640. Asymmetric unit was formed by two Zn(bipy) 2+ 3, disordered Cl - and H 2O exist in the crystal structure.
