| Abstract: | A two-dimensional coordination polymer Zn2(DTB)(DMF)4(H2O)2]n has been synthesized by 1,4-dinitro-2,3,5,6-tetracarboxylatebenzenic acid and hydrate zinc perchlorate in the solutions of DMF and H2O. The crystal belongs to the triclinic system, space group P1 with a = 8.887(6), b = 9.225(6), c = 9.828(7) ?, α = 85.249(11), β = 74.863(11), γ = 86.510(13)°, V = 774.4(9), Z = 1, C22H32N6O18Zn2, Mr = 799.28, Dc = 1.714 g/cm3, F(000) = 410 and μ = 1.639 mm-1. The structure was refined to R = 0.0539 and wR = 0.1161 for 1584 observed reflections (I > 2σ(I)). In the complex there exist two kinds of coordination environments for the zinc(II) ions and a two-dimensional sheet is formed via the coordination of carboxylates and zinc(II) ions. |
