摘要
The reaction of picolinic acid (Hpic) and (n-Bu_4N)_4[Mo_8O_(26)] in thepresence of CH_3CN gave a supramolecular compound (n-Bu_4N)_2[Mo_2O_6(pic)_2] (1), and its structurewas characterized by elemental analysis, IR spectra and single crystal X-ray diffraction analysis.The single crystal X-ray diffraction study shows that the crystal is in monoclinic crystal system,P2_1/c space group with cell parameters a = 0.9941(2), b = 1.3719(2), c = 1.8824(2) nm, β = 100.840(10)°, M_r = 508.50, V = 2.5214(9) nm^3, F(000) = 1072. Compound 1 is a dimer through two μ_2-Obridging to two MoO_3(pic)^- unit, then connected one-dimensional anion-chain by unclassicalhydrogen bonding, and the anion-chain across the channels formed via (n-Bu_4N)^+ cations. By meansof unclassical hydrogen bonding, the anion-chain and cation-channels assemble into three-dimensionalsupramolecular networks.
