ABSTRACT: Single crystals of the title compound, tetra-lutetium(III) tris-(cyclo-tetra-phosphate), Lu(4)(P(4)O(12))(3), were obtained by solid-state reaction. The cubic structure is isotypic with its Al(III) and Sc(III) analogues and is built up from four-membered (P(4)O(12))(4-) phosphate ring anions ( symmetry), isolated from each other and further linked through isolated LuO(6) octa-hedra (.3. symmetry) via corner sharing. Each LuO(6) octa-hedron is linked to six (P(4)O(12))(4-) rings, while each (P(4)O(12))(4-) ring is linked to eight LuO(6) octa-hedra.

ABSTRACT: Single crystals of the title compound, Al(2)P(6)O(18), were obtained by solid-state reaction. The monoclinic structure is isotypic with its Cr(III), Ga(III) and Ru(III) analogues and is built up of six-membered phosphate ring anions, P(6)O(18) (6-), isolated from each other and further linked by isolated AlO(6) octa-hedra by sharing corners. Each AlO(6) octa-hedron is linked to four P(6)O(18) (6-) rings. More accurately, two rings are linked through bidentate diphosphate groups attached in the cis-positions to the AlO(6) octa-hedron. The other two rings are linked to the two remaining corners, also in cis-positions of the AlO(6) octa-hedron.

ABSTRACT: Single crystals of yttrium penta-phosphate(V), YP(5)O(14), were obtained by solid-state reaction. The ortho-rhom-bic 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) tetra-hedra and one branching Q(3)-type PO(4) tetra-hedron, 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) tetra-hedra into a three-dimensional framework.
