An orthorhombic polymorph of the ultraphosphate YP(5)O(14)
Single crystals of yttrium pentaphosphate(V), YP(5)O(14), were obtained by solid-state reaction. The orthorhombic title compound belongs to the family of ultraphosphates and is the second polymorph of this composition. It is isotypic with its Ho and Er analogues. The structure contains two bridgi...

Sumario: | Single crystals of yttrium pentaphosphate(V), YP(5)O(14), were obtained by solid-state reaction. The orthorhombic title compound belongs to the family of ultraphosphates and is the second polymorph of this composition. It is isotypic with its Ho and Er analogues. The structure contains two bridging Q (2)-type PO(4) tetrahedra and one branching Q (3)-type PO(4) tetrahedron, leading to infinite ultraphosphate ribbons running along the a axis. The coordination polyhedron around the Y(3+) cation may be described as distorted bicapped trigonal-prismatic. The YO(8) polyhedra are isolated from each other. They are linked by corner-sharing to the O atoms of six Q (2)-type and of two Q (3)-type PO(4) tetrahedra into a three-dimensional framework. |
