A new molybdenum complex (C4H12N2)2[(MoV2O4)(MoVIO4)(C2O4)2]·2H2O, was solvothermally synthesized and characterized by single-crystal X-ray diffraction. The structure of the compound consists of oxalate acid-coordinated mixed-valent [MoV2O4][MoVIO4] helical chains and protonated piperazine cations. The helical chains are built up from the [MoV2O4] units and [MoVIO4] tetrahedral. The central axis about helical chain is a 2-fold screw axis. The compound crystallizes in the space group P21/n of monoclinic system with a = 11.396(2) Å, b = 14.107(3) Å, c = 15.805(3) Å, β = 102.09(3)°, V = 2484.6(9) Å3, Z = 4. Other characterizations by elemental analysis, IR, and thermal analysis for this compound are also given.
