Dipotassium samarium(III) molybdate(VI) phosphate(V), K(2)Sm(MoO(4))(PO(4)).

ABSTRACT: The title compound, K(2)Sm(MoO(4))(PO(4)), has been prepared under atmospheric conditions using a high temperature solution growth (HTSG) method. The structure of K(2)Sm(MoO(4))(PO(4)) is isotypic with other A(2)M(MoO(4))(PO(4)) compounds, where A = Na or K, and M = trivalent rare earth cation. It can be described as being built up from two-dimensional anionic layers with composition [Sm(MoO(4))(PO(4))](2-) that are stacked along the c axis and are inter-connected by K(+) cations which are in an eightfold coordination by O atoms. The SmO(8), MoO(4) and PO(4) polyhedra exhibit 2 symmetry.

Lithium europium(III) molybdate(VI), Li(3.5)Eu(1.5)(MoO(4))(4).

Project description:The title compound, Li(3.5)Eu(1.5)(MoO(4))(4), was prepared by solid-state reactions. The fundamental building units of the structure are LiO(4) polyhedra (site symmetry [Formula: see text]), distorted LiO(6) polyhedra and MoO(4) tetra-hedra, which are further inter-connected via corner-sharing O atoms. One site is occupied by both Li and Eu atoms in a substituent disordered manner (0.25:0.75), and the Li/Eu atoms are coordinated by eight O atoms in a distorted square-antiprismatic manner.

Dipraseodymium(III) pyroborate molybdate(VI), Pr(2)(B(2)O(5))(MoO(4)).

Project description:Single crystals of triclinic Pr(2)(B(2)O(5))(MoO(4)) were prepared from an incongruently melting flux in the system Pr(2)O(3)-MoO(3)-B(2)O(3) in a platinum crucible in an atmosphere of air. In the crystal structure, distorted edge-sharing [PrO(8)] square anti-prisms form a three-dimensional framework. These are further linked by isolated [MoO(4)] tetra-hedra and isolated pyroborate groups [B(2)O(5)], the latter consisting of two independent trigonal [BO(3)] groups sharing one O atom. The [MoO(4)] tetra-hedra and the [B(2)O(5)] groups are arranged in alternating layers parallel to the ab plane.

Neodymium(III) molybdenum(VI) borate, NdBO(2)MoO(4).

Project description:Single crystals of NdBO(2)MoO(4) were obtained from a molybdenum oxide-boron oxide flux under an air atmosphere. The structure features double chains of edge- and face-sharing distorted [NdO(10)] bicapped square-anti-prisms, which are linked by rows of isolated [MoO(4)] tetra-hedra and by zigzag chains of corner-sharing [BO(3)] groups, all of them running along the b axis. The chains of [NdO(10)], chains of [BO(3)] and rows of [MoO(4)] groups are arranged in layers parallel to the bc plane.

Sodium samarium tetra-kis-(poly-phosphate), NaSm(PO(3))(4).

Project description:NaSm(PO(3))(4) has been prepared by solid state reactions. It belongs to type II of the structural family of M(I)Ln(III)(PO(3))(4) compounds (M(I) = alkali metal and Ln(III) = rare earth metal) and is composed of (?)(PO(3))(n)](n-) polyphosphate chains with a repeating unit of four PO(4) tetra-hedra. The chains extend parallel to [100] and share O atoms with irregular SmO(8) polyhedra, forming a three-dimensional framework which delimits tunnels occupied by Na(+) cations in a distorted octa-hedral environment.

The lanthanum(III) molybdate(VI) La(4)Mo(7)O(27).

Project description:Crystals of the ortho-rhom-bic phase La(4)Mo(7)O(27) (lanthanum molybdenum oxide) were obtained from a non-stoichiometric melt in the pseudo-ternary system La(2)O(3)-MoO(3)-B(2)O(3). In the crystal structure, distorted square-anti-prismatic [LaO(8)] and monocapped square-anti-prismatic [LaO(9)] polyhedra are connected via common edges and faces into chains along [010]. These chains are arranged in layers that alternate with layers of [MoO(4)] and [MoO(5)] polyhedra parallel to (001). In the molybdate layers, a distorted [MoO(5)] trigonal bipyramid is axially connected to two [MoO(4)] tetra-hedra, forming a [Mo(3)O(11)] unit.

Scheelite-type sodium neodymium(III) ortho-oxidomolybdate(VI), NaNd[MoO(4)](2).

Project description:Scheelite-type NaNd[MoO(4)](2) contains one crystallographic position (site symmetry [Formula: see text]) for the large cations, which is mixed-occupied by Na(+) and Nd(3+) cations in a 1:1 molar ratio. Thus, both are surrounded by eight O atoms in the shape of a trigonal dodeca-hedron. Furthermore, the structure consists of crystallographically unique [MoO(4)](2-) units (site symmetry [Formula: see text]) surrounded by eight sodium and neodymium cations, which are all vertex-attached. The polyhedra around the Na(+)/Nd(3+) cations are connected to four others via common edges, building up a three-dimensional network in whose tetra-hedral voids of O atoms the Mo(6+) cations reside.

The defect scheelite-type lanthanum(III) ortho-oxidomolybdate(VI) La(0.667)[MoO(4)].

Project description:In scheelite-type La(0.667)[MoO(4)], one crystallographically unique position with site symmetry -4.. and an occupancy of 2/3 is found for the La(3+) cation. The cation is surrounded by eight O atoms in the shape of a trigonal dodeca-hedron. The structure also contains one [MoO(4)](2-) anion (site symmetry -4..), which is surrounded by eight vertex-attached La(3+) cations. The polyhedra around the La(3+) cations are inter-connected via common edges, building up a three-dimensional network, in the tetra-hedral voids of which the Mo(6+) cations reside.

Dipotassium dialuminium cyclo-octa-phosphate.

Project description:Single crystals of the title compound, K(2)Al(2)P(8)O(24), were obtained by solid-state reaction. The monoclinic structure is isotypic with that of the Ga(III) analogue and is built of eight-membered phosphate ring anions P(8)O(24) (8-) (2/m symmetry) isolated from each other and further linked by isolated AlO(6) octa-hedra ( symmetry) by sharing corners. Each AlO(6) octa-hedron is linked to four P(8)O(24) (8-) rings in such a way that two rings are linked through bidentate diphosphate groups attached in the cis positions on two opposite parallel edges of the octa-hedron. The two other rings are linked via corner-sharing to the two remaining corners in the trans positions of the AlO(6) octa-hedron. Each P(8)O(24) (8-) ring anion is linked to eight AlO(6) octa-hedra. More accurately, each ring anion is linked to four AlO(6) octa-hedra through bidentate diphosphate groups attached in the cis positions to the AlO(6) octa-hedron and to the four remaining octa-hedra by sharing corners. This three-dimensional linkage delimits channels running parallel to [001] in which the ten-coordinated K(+) cations (2 symmetry) are distributed over two columns. These columns alternate with empty octa-gonally-shaped channels expanding through the P(8)O(24) (8-) ring anions.

Lithium vanado(V)molybdate(VI), Li[VMoO6].

Project description:Brannerite-type Li[VMoO6] has been synthesized by a solid state reaction route. The V and Mo atoms statistically occupy the same site with mirror symmetry and are octa-hedrally surrounded by O atoms. The framework is two-dimensional and is built up from edge-sharing (V,Mo)O6 octa-hedra forming (VMoO6)? layers that run parallel to the (001) plane. Li(+) ions are situated in position with symmetry 2/m in the inter-layer space. The bond-valence analysis reveals that the Li(+) ionic conductivity is along the [010] and [110] directions, and shows that this material may have inter-esting conduction properties. This simulation proposes a model of the lithium conduction pathways.
