Abstract:By using rigid ligands, 2-(4,5-Diphenyl-1H-imidazole)-4-thiophene(L)as an organic building unit,we obtained two supramolecular compounds under hydrothermal conditions based on different polyoxometalates, [H4L4(Mo8O26)].2H2O (1) and [H6L8(PMo12)]2 (2), and characterized them by single-crystal X-ray diffraction, elemental analysed and IR spectra.Structural analyses show that compound 1 and compound 2 crystallizes in space group P(1).compound 1;a=13.196(5)(A), b=13.476(5)(A), c=14.198(5)(A), α=62.637(5) °, β=74.915(5) °, γ=84.457(5) °, V=2164.3(14)(A)3, Z=1,R1=0.0699, R2=0.2064.compound 2;a=17.215(5)(A), b=23.028(5)(A), c=24.979(5)(A), α=90.303(5) ° , β=91.009(5) °, γ=92.359(5) °, V=9892(4)(A)3, Z=2, R1=0.1006, R2=0.2929.In the two compounds, the L ligand surrounds the POMs anion and forms a supramolecular framework by hydrogen bonding.
