A Metal-organic Framework with Alternately Hydrophilic and Hydrophobic Layers Based on Tetrazole Derivative:Synthesis, Structure and Luminescent Property

摘要

A new metal-organic framework based on ethyl lH-tetrazole-5-acetate(Hetza),[Ag4(etza)4](1),has been synthesized and characterized by elemental analysis,IR,thermal gravimetric and X-ray structural analysis.Crystal data for the title complex are as follows:triclinic system,space group P1 with α = 11.0771(6),b = 11.6636(6),c = 13.2925(8),α = 102.3710(10),β=103.3810(10),γ = 90.0890(10)°,V= 1629.60(16) A3,Mr = 1052.06,Z = 2,F(000) = 1024,Dc =2.144 g/cm3,μ(MoKα) = 2.438 mm-1,the final R = 0.0538 and wR = 0.1475(I> 2σ(I)).Complex 1adopts the(4·82) topological network and the alternately hydrophilic-hydrophilic and hydrophobic-hydrophobic arrangements.The luminescent properties of complex 1 and the free Hetza ligand have been studied in the solid states.
