Hydrothermal reaction between mixed ligand(1,2,4-triazole and benzoic acid) and Zn(NO3)2·6H2O afforded a three-dimensional(3D) metal-organic framework Zn3(C2H2N3)2(C7H5O2)4(C2H2N3=1,2,4-triazole,C7H5O2=benzoic acid).The compound was crystallized in the hexagonal system with space group R3:a=2.90234(9) nm,b=2.90234(9) nm,c=1.08597(5) nm,γ=120°,V=7.9222(5) nm3,Mr=816.68,Dc=1.541 g/cm3,Z=9,F(000)=3708,R=0.0636,and wR=0.1777.Its structure consists of ZnN2O2 tetrahedron and ZnN2O4 octahedron,which are connected by 1,2,4-triazole and benzoic acid ligands to form a 3D framework with helical units.This compound forms an inter-penetrated NbO topology.The compound was characterized by single-crystal X-ray diffraction,elemental analysis,FTIR spectra,and TGA measurements.
Hydrothermal reaction between mixed ligand (1,2,4-triazole and benzoic acid) and Zn (NO3) 2 · 6H2O afforded a three-dimensional (3D) metal-organic framework Zn3 (C2H2N3) 2 (C7H5O2) 4 , 2,4-triazole, C7H5O2 = benzoic acid. The compound was crystallized in the hexagonal system with space group R3: a = 2.90234 (9) nm, b = 2.90234 (9) nm, γ = 120 °, V = 7.9222 (5) nm3, Mr = 816.68, Dc = 1.541 g / cm3, Z = 9, F (000) = 3708, R = 0.0636, and wR = 0.1777.Its structure consists of ZnN2O2 tetrahedron and ZnN2O4 octahedron, which are connected by 1,2,4-triazole and benzoic acid ligands to form a 3D framework with helical units. This compound forms an inter-penetrated NbO topology. The compound was characterized by single-crystal X-ray diffraction , elemental analysis, FTIR spectra, and TGA measurements.
