摘要

通过水热反应合成了一种新型镎(VI)磷酸盐化合物 (NpO2)3(PO4)2(Terpy)。它在正交空间群 Pca21 中结晶，单位晶胞参数为 a = 13.9944 Å、b = 12.1989 Å、c = 13.1277 Å、V = 2241.1 Å3 和 Z = 4。与乌拉诺芬拓扑的层状结构有关，它包含了首次报道的 (NpVIO2)2(PO4)22- 片层，这些片层通过垂直于片层的 NpVIO2(Terpy)2+ 配体之间的 π-π 相互作用结合在一起。

Hydrothermal synthesis and structure of organically templated layered neptunyl(vi) phosphate (NpO2)3(PO4)2(Terpy)†

A novel neptunyl(VI) phosphate compound, (NpO₂)₃(PO₄)₂(Terpy), was synthesized by hydrothermal reaction. It crystallizes in the orthorhombic space group Pca2₁ with unit-cell parameters a = 13.9944 Å, b = 12.1989 Å, c = 13.1277 Å, V = 2241.1 Å³, and Z = 4. Related to the layered structure of the uranophane topology, it contains the first reported (Np^VIO₂)₂(PO₄)₂²⁻ sheets, which are bonded via π–π interactions between the Np^VIO₂(Terpy)²⁺ ligands that are perpendicular to the sheets.
