The reaction of picolinic acid (Hpic) and ( n Bu 4N) 4[Mo 8O 26 ] in the presence of CH 3CN gave a supramolecular compound ( n Bu 4N) 2[Mo 2O 6(pic) 2] (1), and its structure was 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, P 2 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 O bridging to two MoO 3(pic) - unit, then connected one dimensional anion chain by unclassical hydrogen bonding, and the anion chain across the channels formed via ( n Bu 4N) + cations. By means of unclassical hydrogen bonding, the anion chain and cation channels assemble into three dimensional supramolecular networks.
