Abstract: A new layered mixed-valence vanadium oxide, [CH3NH3]2[(VO)2(VO4)2], which contains interlamellar organic cations was prepared under hydrothermal conditions and its single-crystal structure was determined. It crystallizes in a triclinic system with space group P1, a=0.625 59(8) nm, b=0.639 84(9) nm, c=0.747 19(10) nm, α=78.718(2)°, β=80.099(2)°, γ=77.100(2). The compound contains mixed-valence V4+/V5+ vanadium oxide layers constructed from VO4 tetrahedra, pairs of edge-sharing VO5 square pyramid and methylamine with protonated organic amines occupying the interlayer space.
