[NC₄H₁₂]₂[(UO₂)₆(H₂O)₂(SO₄)₇]: the first organically templated actinide sulfate with a three-dimensional framework structure

Abstract

[NC4H12][(UO2)6(H2O)2(SO4)7] is the first organically templated actinide sulfate with a three-dimensional framework structure; it has channels of dimensions 8.5 A x 8.5 A, running along the [001] direction, containing tetramethylammonium cations.

Synthesis, Crystal Structure, and Magnetic Properties of a Three‐Dimensional Hydroxide Sulfate: Mn5(OH)8SO4

“…[28] O. Hare et al have synthesized several uranium sulfates, one of which has a 3D structure. [29][30][31] Metal sulfates without entrained organic cations also exhibit interesting catalytic, ion-exchange, and magnetic properties, and they have higher thermal stability relative to metal sulfate hybrids.…”

Comparative study of the flexibility of structural complexes in uranyl sulfates, chromates, and molybdates

“…At least ten types of three-dimensional framework structures formed by UO 7 pentagonal bipyramids and MoO 4 tetrahedra sharing common vertices are known [139]. On the contrary, sulfates and chromates commonly form chain and lamellar structures [10 314], with framework structures being relatively seldom [15,16].…”

“…At least ten types of three-dimensional framework structures formed by UO 7 pentagonal bipyramids and MoO 4 tetrahedra sharing common vertices are known [139]. On the contrary, sulfates and chromates commonly form chain and lamellar structures [10 314], with framework structures being relatively seldom [15,16].In this work, we attempted a quantitative study of the flexibility of structural complexes in uranyl sulfates, chromates, and molybdates, based on available data on U3O br 3T bond angles and T3O bond lengths. We considered only structural complexes in which the UO n polyhedra (n = 6, 7) and TO 4 tetrahedra share common vertices (an example is shown in Fig.…”

“…Several metal sulfates with varying dimensionality (1D, 2D and 3D) have been synthesized for their interesting physical properties and applications [1][2][3][4][5][6][7][8][9]. There areseveral examples of zero dimensional discrete metal sulfates [10][11][12][13][14][15][16][17][18][19].E arlier Xu et 4 ]·6H 2 Ou sing 4,4'-bipyridine (4,4'-bpy)a s the directing ligand under hydrothermal conditions [19].In2006, Zhao et.al.,synthesized aFe(III) sulfate dimer containing 1,10-phenanthroline as ligand [20].…”
