Abstract

Three new uranium arsonate compounds, UO ₂(C ₆H ₅) ₂As ₂O ₅(H ₂O) (UPhAs-1), UO ₂(HO ₃AsC ₆H ₄AsO ₃H) (H ₂O) ·H ₂O (UPhAs-2), and UO ₂(HO ₃AsC ₆H ₄NH ₂) ₂· H ₂O (UPhAs-3) have been synthesized under mild hydrothermal conditions. UPhAs-1 is constructed from UO ₇ pentagonal bipyramids that are chelated by the pyroarsonate moiety, [PhAs(O ₂)OAs(O ₂)Ph] ^2-, forming chains of layered uranyl polyhedra. Two of the phenylarsonic acids are condensed in situ to form the fused tetrahedra of the pyroarsonate moiety through a metal-mediated, thermally induced condensation process. The structure of UPhAs-2 consists of UO ₇ pentagonal bipyramids that are chelated by phenylenediarsonate ligands, forming one-dimensional chains of uranyl polyhedra. UPhAs-3 consists of a rare UO ₆ tetragonally distorted octahedron (D _4h) that is on a center of symmetry and linked to two pairs of adjacent 4-aminophenylarsonate ligands. This linear chain structure is networked through hydrogen bonds between the lattice water molecules and the -NH ₂ moiety. All three of these compounds fluoresce at room temperature, showing characteristic vibronically coupled charge-transfer based emission.
