MoO-O (NaNH4Mo3O10) was synthesized using tetramethylammonium hydroxide, and MoO-1(C6H18N2-Mo4O13) was synthesized using 1,6-hexanediamine. The two crystal structures have been determined by the single-crystal X-ray diffraction method. Both consist of bundles of parallel molybdenum oxide chains interspersed with metals or organic cations which play the role of intercalating agent in the host structure. The Mo has a 6+ valence state and distorted octahedral coordination. Mo-0 has orthorhombic symmetry (Pnma, No. 62) with a = 8.407(2) Å, b = 7.603(2) Å, and c = 14.350(3) Å. MoO-1 has triclinic symmetry (P1̄, No. 2) with a = 8.267(2) Å, b = 8.986(2) Å, c = 12.714(3) Å, α = 87.58(3)°, β = 76.48(3)°, γ = 67.97(3)°. The study suggests that the structures and properties of intercalation-type molybdenum oxide polymers can be engineered by incorporating the structure-directing units, acidity, and the hydrothermal conditions.||Source Title:||Chemistry of Materials||URI:||http://scholarbank.nus.edu.sg/handle/10635/94092||ISSN:||08974756|
