Vanadium Phosphate Framework Solid Constructed of Octahedra, Square Pyramids, and Tetrahedra with a Cavity Diameter of 18.4 Å

Abstract

Large cavities with segregated hydrophobic and hydrophilic domains result from the inclusion of inorganic and organic canons in the hydrothermal synthesis of the blue compound 1. Its structure is shown in the picture on the right.

A Nickel Molybdenum Phosphate with Tunnel: Hydrothermal Synthesis and Structure of (NH3CH2CH2NH3)4 · (NH3CH2CH2NH2) · Na · [Ni2Mo12O30(PO4)(HPO4)4(H2PO4)3] · 6H2O

“…An investigation on the microporous property is in progress. Since it is di$cult to determine the positions of the nine protons in 1, these nine protons are assumed to associate with ethylenediamine molecules (20).…”

Hydrothermal synthesis and characterization of a new 3D vanadium(III) phosphite (C4H8N2H4)0.5(C4H8N2H3)[V4(HPO3)7(H2O)3]1.5H2O

“…Hydrothermal synthesis has been successful for the preparation of microporous materials and other important solids. A variety of 1D chain [1][2][3][4], 2D layer [1,[5][6][7][8][9], and 3D open-framework structure [10][11][12][13][14][15][16][17][18][19][20][21][22][23] vanadium phosphates were prepared in the presence of organic amine, and alkali metal cation or metal complex as structure-directing agents. It is interesting that [HN(CH 2 CH 2 ) 3 3 ] 2À unit may lead to novel connectivity patterns compared to those observed in vanadium phosphates containing tetrahedral PO 4 units.…”

A New Vanadium Oxide Bronze: [NH3(CH2)6NH3]10[V15O37(Cl)]2[V15O36(Cl)](OH)3(H2O)3 with Clusters [V15O36(Cl)]5− and [V15O37(Cl)]6− Textured by Diaminohexane

“…Atomic coordinates and equivalent temperature factors are given in Table 2. Accordingly, the formulation of the new hybrid (2) 0.085 (7) 10 [ (1) values. This feature arises probably from some kind of dynamic disorder frequently observed in such mesostructured organic/inorganic hybrids.…”
