A novel complex CoL2 ( H2 O) 2 ( L= 2_chloronicotinate) was synthesized by hy_drothermal reaction and characterized by elemental analysis,IR,TG and X_ray single crys_tal diffraction. The title complex in monoclinic with space group P2(1)/c,Mr=407. 05, a=0. 74303(9) nm,b=1. 23224(15) nm,c=0. 75773(9)nm,V=0. 67427(1) nm3, Z=2,Dc=1. 970 g/m3 ,F(000) =410,S=1. 073. The six_coordinated geometry of the Co (Ⅱ) is in a octahedron configuration. A two_dimensional network structure is constructed by ∏_∏ stacking interaction and intermolecular hydrogen bonds between single cells.
