A novel zinc(II) complex [Zn(L) 2(H 2O) 2](CH 3COO) 2·2H 2O (1) was obtained by self assembly of tripodal ligand 1,3,5 tris(1 imidazolyl)benzene (L) with Zn(CH 3COO) 2·2H 2O. The structure of the complex was determined by X ray diffraction analysis. Crystal data for 1 monoclinic, P 2 1/ n , a =0 8339(1) nm, b =1 2209(2) nm, c =1 7565(3) nm, β =94 880(3)°, Z =2, V =1 7819(5) nm 3, D c=1 383 g/cm 3, μ =1 505 mm -1 , F (000)=1560, R 1=0 0429, wR 2=0 0713. The complex has two dimensional network structure. The acetate anions occupy the vacancy between the 2D layers and can be exchanged by other anions such as nitrate.
