The reaction of picolinic acid (Hpic) and ( n ‐Bu 4 N) 4 [Mo 8 O 26 ] in the presence of CH 3 CN gave a supramolecular compound ( n ‐Bu 4 N) 2 [Mo 2 O 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 4 N) + cations. By means of unclassical hydrogen bonding, the anion‐chain and cation‐channels assemble into three‐dimensional supramolecular networks.
