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

ABSTRACT: 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.

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.

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

Project description: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.

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.

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.

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.

Bis(isopropyl-ammonium) tetra-sulfido-molybdate(VI).

Project description:The title compound, (C(3)H(10)N)(2)[MoS(4)], was synthesized by passing a rapid stream of H(2)S into an aqueous isopropyl-amine solution of molybdic acid. The title compound is isotypic with the corresponding W analogue (C(3)H(10)N)(2)[WS(4)]; its structure consists of a slightly distorted tetra-hedral [MoS(4)](2-) dianion and two crystallographically independent isopropyl-ammonium cations, with all atoms located in general positions. The cations and anion are linked by weak N-H⋯S and C-H⋯S inter-actions, the strength and number of which can explain the observed Mo-S bond distances.

Tetra-kis(2-methyl-benzimidazolium) ?-octa-molybdate(VI).

Project description:The asymmetric unit of the title compound, (C(8)H(9)N(2))(4)[Mo(8)O(26)], consists of two 2-methyl-benzimidazolium cations and one-half of a ?-Mo(8)O(26) (4-) anion, which is completed by crystallographic inversion symmetry. An extensive net of N-H?O hydrogen bonds between the cations and anions contribute to the crystal packing.

Tetra-ammonium diaqua-diperoxidoocta-molybdate(VI) tetra-hydrate.

Project description:The title compound (NH(4))(4)[Mo(8)O(24)(O(2))(2)(H(2)O)(2)]·4H(2)O, consists of an octa-molybdate cluster with a crystallographic centre of symmetry. The clusters pack in a cubic close packing arrangement defining channels containing water mol-ecules and ammonium cations, which exhibit hydrogen bonding with neighbouring clusters. Hydrogen bonding also exists between the coordinated water mol-ecules of one cluster with one of the O atoms of the peroxido fragment in a neighbouring cluster.
