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

ABSTRACT: 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.

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 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.

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.

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.

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.

Ba(11)La(4)Br(34): a new barium lanthanum bromide.

Project description:The structure of the title compound, barium lanthanum bromide (11/4/34), can be derived from the fluorite structure. The asymmetric unit contains two Ba sites (one with site symmetry 4/m..), one La site (site symmetry 4..), one mixed-occupied Ba and La site (ratio 1:1, site symmetry m..) and six Br sites (one with site symmetry \=4.., one with 2.., one with m.., the latter being disordered over two positions with a 0.86:0.14 ratio). The fundamental building units of the structure are edge-sharing polyhedral clusters made up of Ba and La bromide clusters inter-connected to BaBr(8) square prisms and BaBr(10) groups.

Scheelite-type NaEr(MoO(4))(2).

Project description:Explorations of the A(1+)-RE(3+)-Mo(6+)-O(2-) (A(1+) is an alkali metal cation, RE(3+) is a rare-earth metal cation) quaternary systems prepared by the high-temperature solution growth method led to the title structure, sodium erbium bis-(molyb-date), NaEr(MoO(4))(2). It is isostructural to the scheelite structure (CaWO(4)) and is composed of [MoO(4)](2-) tetra-hedra with symmetry and [(Na/Er)O(8)](14-) polyhedra. The [(Na/Er)O(8)](14-) polyhedron is a distorted tetra-gonal anti-prism, also with symmetry, with statistically mixed Na/Er atoms at its centre. There are two sets of Na/Er-O bond lengths [2.420?(4) and 2.435?(3)?Å], but just one set of Mo-O bond lengths [1.774?(4)?Å].

Project description:La(21)Ru(9+x)In(5-x) (Pearson symbol tI140) is isotypic to the filled Y(3)Rh(2)-type structure, from which it can be derived through an ordered substitution at two sites. One of the square-prismatic sites (site symmetry ..m) is occupied by a mixture of Ru and In atoms and one of the square-antiprismatic sites (4/m..) is fully occupied by In atoms.

Hexa-?-chlorido-hexa-chlorido(?-hexa-methyl-benzene)trialuminium(III)lanthanum(III) benzene solvate.

Project description:In the title compound, [Al(3)LaCl(12)(C(12)H(18))]·C(6)H(6), all mol-ecules are located on a mirror plane. Three chloridoaluminate groups and a hexa-methyl-benzene mol-ecule are bound to the central lanthanum(III) ion, forming a distorted penta-gonal bipyramid with the ?(6)-coordinated arene located at the apical position. The hexa-methyl-benzene ligand disordered between two orientations in a 1:1 ratio is also involved in parallel-slipped ?-? stacking inter-molecular inter-actions with a benzene solvent mol-ecule [centroid-centroid distance 3.612?(4)?Å].
