摘要：

A new 2D Zn(Ⅱ) coordination polymer [Zn(TAU)2]n (1, HTAU=2-aminoethane- sulfonic acid) constructed by 2-aminoethanesulfonic acid ligand has been hydrothermally synthesized by the reaction of Zn(CH3COO)2 and 2-aminoethanesulfonic acid with a 1:2 mole ratio and characterized by single-crystal X-ray diffraction, elemental analysis, infrared spectroscopy and thermogravimetric analysis. Crystal structural analysis reveals it crystallizes in monoclinic, space group P21/c with a=8.672(4), b=6.523(3), c=9.134(5) , β=115.441(5)°, V=466.6(4) 3, Mr=313.65, Z=2, Dc=2.232 Mg·m-3, F(000) =320, μ(MoKα)=3.091 mm-1, the final R=0.0358 and wR=0.0919 for 2026 observed reflections with Ⅰ > 2σ(Ⅰ). In the structure, each zinc(Ⅱ) ion is coordinated in a slightly distorted octahedron, and each μ3-TAU– acts as a bridge to bond three neighboring Zn(Ⅱ) ions to form an infinite 2D network structure.
