Lutetium ultraphosphate
The structure of the title compound, LuP(5)O(14), comprises puckered eight-membered PO(4) rings linked by the lutetium cations in a complex way, forming a three-dimensional framework. Each eight-membered phosphate ring shares a bridging tetra-hedron with each of four adjacent tetra-hedra, to form layers of PO(4) tetra-hedra. These layers are c/2 in thickness and parallel to the ab plane. Each L...
متن کاملAn orthorhombic polymorph of the ultraphosphate YP5O14
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 infinit...
متن کاملHydrogen relaxation in lutetium
2014 The internal friction and the dynamic modulus have been measured between 4.2 and 470 K in the system 03B1-LuH(D)x, with x = 0 to 0.2. In well annealed specimens, an (H)-peak is observed at 215-225 K, which has a linearly x-dependent amplitude and exhibits an isotope effect on its activation energy and relaxation time. It is attributed to a Snoek-like relaxation of H-H pairs reorienting in ...
متن کاملLutetium(III) cyclotetraphosphate
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. symmetr...
متن کاملChiral lutetium benzamidinate complexes.
Enantiomerically pure lutetium complexes were synthesized as the first rare earth metal complexes containing a chiral amidinate ligand. The catalytic activity and the enantioselectivity in hydroamination reactions were studied.
