Synthesis, Structure and Ion-exchange Property of Zinc(II) Complex with a Novel Tripodal Ligand 1,3,5-Tris(1-imidazolyl) benzene

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(l- 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, P2_1/n, a = 0.8339(1) nm, 6 = 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.
