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

ABSTRACT: 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.

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.

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].

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.

catena-Poly[neodymium(III)-bis-[?-N-(dimorpholinophosphor-yl)benzene-sulfonamidato]-sodium(I)-bis-[?-N-(dimorpholinophosphor-yl)benzene-sulfonamidato]].

Project description:The cubic crystal structure of the title compound, [NaNd(C(14)H(21)N(3)O(5)PS)(4)](n), is composed of one-dimensional polymeric chains propagating in [100], built up from [Nd(C(14)H(21)N(3)O(5)PS)(4)](-) anions and sodium cations functioning as linkers. In the complex anion, the Nd(3+) ion has an eightfold coordination environment formed by the sulfonyl and phosphoryl O atoms of four bidentate chelating N-(dimorpholinophosphor-yl)benzene-sulfonamidate ligands: the resulting NdO(8) polyhedron can be described as inter-mediate between dodeca-hedral and square anti-prismatic. The sodium ion adopts an NaO(4) tetra-hedral geometry arising from four monodentate benzene-sulfonamidate ligands. The resulting crystal structure is unusual because it contains substantial voids (800?Å(3) per unit cell), within which there is no evidence of included solvent.

Poly[aqua(?(3)-5-aza-niumylisophthalato)-(?-oxalato)neodymium(III)].

Project description:The title compound, [Nd(C(8)H(6)NO(4))(C(2)O(4))(H(2)O)](n), is a layer-like coordination polymer. The Nd(III) ion is coordinated by four carboxyl-ate O atoms from three bridging 5-aza-nium-yl-isophthalate (Haip) ligands, four carboxyl-ate O atoms from two oxalate (ox) anions and one ligated water mol-ecule in a tricapped trigonal-prismatic geometry. The Haip anion acts as a ?(3)-bridge, connecting three Nd(III) ions through two carboxyl-ate groups; the ox anion adopts a bis-bidentate-bridging mode, linking two Nd(III) ions. The layer framework is further extended to a three-dimensional supra-molecular structure through N-H?O and O-H?O hydrogen bonds.
