| Abstract: A novel complex based on Zn (II) and terphenyl-2, 2', 4, 4'-tetracarboxylic acid, namely, [Zn2(tpta)0.5(H2tpta)(dpe)(H2O)2]n (H4tpta = terphenyl-2, 2', 4, 4'-tetracarboxylic acid, dpe = 1,2-di(4-pyridyl)ethylene) has been hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, single-crystal X-ray diffraction analysis, thermal stability analysis and fluorescent analysis. The complex crystallizes in triclinic system, space group P ī with a = 1.0174(2) nm, b = 1.0341(2) nm, c = 1.8831(4) nm, α = 96.147(4)，β = 96.866(4)，γ = 98.023(4)，V = 1.9322(7) nm3, Z = 2, Dc = 1.640 Mg?m-3, μ =1.320 mm-1, F(000) = 974 , and the final R1= 0.0669, wR2 = 0.1332 for I >2σ(I). Complex 1 features an unusual 2D bilayer motif with ring dinuclear Zn2 units, which is further linked to each other by O–H???O hydrogen bonds to complete the final 3D supramolecular architecture. In additional, complex 1 shows good thermal stability and luminescent property. CCDC: 913522. |
