A New Coordination Polymer Built of 4-(5H-tetrazol)-benzoic Acid and 3,5-Dimethyl-1H,1,2,4-Triazole Showing a Rarely Observed (3,5)-Connected lhh Topology: Synthesis,Structure, CO2 Adsorption and Luminescent Property

摘要

A three-dimensional coordination polymer,namely {[Zn_2(tzba)(dmtrz)(OH)]·3H_2O}_n(1,H_2tzba = 4-(5H-tetrazol)benzoic acid,Hdmtrz = 3,5-dimethyl-lH,l,2,4-triazole),was hydrothermally synthesized and characterized by single-crystal X-ray diffraction.It crystallizes in monoclinic system,P2_1/c space group with a = 8.018(11),b = 21.04(3),c = 11.069(14) A,β=91.26(3)°,V= 1867(4) A^3,Z = 4,D_c = 1.729 g/cm^3,F(000) = 984,μ= 2.614 mm^(-1),R(F^2 > 2σ(F^2)) =0.0612 and wR(F^2) = 0.1533.Topological analysis reveals that compound 1 is a(3,5)-connected structure with a Schlafli symbol of(4~2.6)(4~2.6~5.8~3),which is a rarely observed lhh topology.In addition,the CO_2 adsorption performance and luminescent property of 1 have also been studied.
