Tetra-potassium dianti-mony(III) tin(IV) tetra-deca-fluoride.

ABSTRACT: The title compound, K(4)Sb(2)SnF(14), is built from anionic layers, with an overall composition of [Sb(2)SnF(14)](4-) extending parallel to the ac plane, and K(+) cations. The layers are made up from vertex-sharing centrosymmetric SnF(6) octa-hedra and Sb(2)F(12) dimers. The Sn-F distances are in the range 1.9581?(14)-1.9611?(17)?Å. The Sb polyhedra contain three short terminal Sb-F bonds [1.9380?(14)-2.0696?(15)?Å], one short bridging bond [2.0609?(17)?Å], one bridging bond of medium length [2.7516?(15)?Å], and two longer bridging bonds [3.0471?(18) and 3.117?(2)?Å]. The K(+) ions are coordinated by F atoms with coordination numbers 10 and 8, and K-F bond lengths are in the range 2.6235?(16)-3.122?(2)?Å.

Penta-potassium praseodymium(III) dilithium deca-fluoride, K(5)PrLi(2)F(10).

Project description:The crystal structure of K(5)PrLi(2)F(10) is isotypic with those of other K(5)RELi(2)F(10) compounds (RE = Eu, Nd). The lanthanoid ions are isolated in K(5)PrLi(2)F(10), with a mean separation between the Pr ions of 7.356?Å. It classifies this crystal as a so-called self-activated material containing lanthanoid ions within the matrix. Except for two K(+) and two F(-) ions, all atoms are located on sites with m symmetry. In the structure, distorted PrF(8) dodeca-hedra and two different LiF(4) tetra-hedra share F atoms, forming sheets parallel to (100). The isolated PrF(8) dodeca-hedra exhibit a mean Pr-F distance of 2.406?Å. The K(+) cations are located within and between these sheets, leading to highly irregular KF(x) polyhedra with coordination numbers of eight and nine for the alkali metal cations.

Penta-potassium europium(III) dilithium deca-fluoride, K(5)EuLi(2)F(10).

Project description:The title compound, K(5)EuLi(2)F(10), belongs to so-called self-activated materials containing lanthanoid ions within the matrix. A common feature of these systems is a large separation between the closest lanthanoid ions, which is one of the crucial factors governing the self-quenching of luminescence. The crystal structure of K(5)EuLi(2)F(10) is isotypic with other K(5)RELi(2)F(10) compounds (RE = Nd, Pr). As expected from the lanthanoid contraction, the unit-cell volume for crystal with Eu(3+) ions is the smallest of the three structures. Accordingly, the corresponding inter-atomic RE-RE distances are shorter. In the structure, distorted EuF(8) dodeca-hedra and two different LiF(4) tetra-hedra, all with m symmetry, are present, forming sheets parallel to (100). The isolated EuF(8) dodeca-hedra exhibit a mean Eu-F distance of 2.356?Å. The K(+) cations are located within and between the sheets, leading to highly irregular KF(x) polyhedra (x = 8-9) around the alkali metal cations.

Tetra-chloridobis(dibenzyl sulfoxide-?O)tin(IV).

Project description:The six-coordinate Sn(IV) atom in the title compound, [SnCl(4)(C(14)H(14)OS)(2)], exists in a cis-SnCl(4)O(2) octa-hedral geometry. Of the four Cl atoms, two are close to adjacent S atoms [Cl?S = 3.320?(1) and 3.376?(1)?Å]; the Sn-Cl bonds involving these two Cl atoms are longer than the other two Sn-Cl bonds.

trans-Dichlorido(1,4,8,11-tetra-azacyclo-tetra-deca-ne)manganese(III) tetra-fluorido-borate.

Project description:In the title manganese(III) complex, [MnCl(2)(C(10)H(24)N(4))]BF(4) or trans-[MnCl(2)(cyclam)]BF(4) (cyclam is the tetra-dentate amine ligand 1,4,8,11-tetra-azacyclo-tetra-deca-ne), the Mn(III) ions occupy the center of a distorted octa-hedron coordinated by all four ligand nitro-gen donors in the macrobicyclic cavity and two chloride ions occupy the axial positions. Intra-molecular hydrogen bonding involving the coordinated chloride ions and the hydrogen atoms of the cyclam ligand is observed. Inter-molecular hydrogen bonding involving the tetrafluoridoborate anion and hydrogen atoms of the cyclam ligand leads to an infinite one-dimensional chain along the a axis. The tetra-fluoridoborate and inorganic units are linked by N-H?F hydrogen bonds. The structure may be compared with those of analogous compounds [MnCl(2)(cyclam)]ClO(4) and [Mn(CN)(2)(cyclam)]ClO(4).

Monolanthanum tripotassium tetra-hydrogen deca-molybdodicobaltate(III) trideca-hydrate.

Project description:The title compound, K(3)La[H(4)Mo(10)Co(2)O(38)].13H(2)O, is an optically active chiral polyoxometalate (POM) which contains an anion with ideal point symmetry D2 (222). The crystals containing one of the enanti-omer pairs in the POM were resolved at pH 2.5. The factor that governs the formation of the compound is the pH condition of the mother liquor. The racemate salt, K(6)[H(4)Mo(10)Co(2)O(38)]·7H(2)O, is obtained at pH 6.5 [Nolan et al. (1998 ?). Aust. J. Chem.51. 825-834]. Two non-acidic H atoms in the POM form intra-molecular hydrogen bonds and the remaining two H atoms form hydrogen bonds with two water mol-ecules. The POMs are connected by three K(+) ions. The La(3+) ion is coordinated by three O atoms of the POM and six water molecues with distances in the range 2.516?(5)-2.589?(5)?Å.

Bis[tris-(ethyl-enediamine-?N,N')cobalt(III)] octa-kis-?-(3)-oxido-hexa-deca-?(2)-oxido-tetra-deca-oxido-?(12)-tetra-oxo-silicato-octa-molybdenum(VI)hexa-vanadium(IV,V) hexa-hydrate.

Project description:The title compound, [Co(C(2)H(8)N(2))(3)](2)[SiMo(8)V(4)O(40)(VO)(2)]·6H(2)O, was prepared under hydro-thermal conditions. The asymmetric unit consists of a transition metal complex [Co(en)(3)](3+) cation (en is ethyl-enediamine), one half of an [SiMo(8)V(4)O(40)(VO)(2)](6-) heteropolyanion, two solvent water mol-ecules in general positions and two half-mol-ecules of water located on a mirror plane. In the complex cation, the Co(3+) ion is in a distorted octa-hedral coordination environment formed by six N atoms of the three chelating en ligands. One of the en ligands exhibits disorder of its aliphatic chain over two sets of sites of equal occupancy. The [SiMo(8)V(4)O(40)(VO)(2)](6-) heteropolyanion is a four-electron reduced bivanadyl-capped ?-Keggin-type molybdenum-vanadium-oxide cluster. In the crystal, it is located on a mirror plane, which results in disorder of the central tetra-hedral SiO(4) group: the O atoms of this group occupy two sets of sites related by a mirror plane. Furthermore, all of the eight ?(2)-oxide groups are also disordered over two sets of sites with equal occupancy. There are extensive inter-molecular N-H?O hydrogen bonds between the complex cations and inorganic polyoxidoanions, leading to a three-dimensional supra-molecular network.

Tribenzylbis(triphenyl-arsine oxide-?O)tin(IV) tetra-phenyl-borate.

Project description:The crystal structure of the title salt, [Sn(C(7)H(7))(3)(C(18)H(15)AsO)(2)][B(C(6)H(5))(4)], consists of discrete cations and anions; the tin atom of the cation is five-coordinated in a distorted trans-C(3)SnO(2) trigonal-bipyramidal geometry [summation of C-Sn-C angles 360.0?(3)° and O-Sn-O angle 173.1?(1)°]. The structure contains voids of 113?(19)?Å(3), but no solvent mol-ecule could reasonably be located there.

Project description:The title mol-ecule, [Sn(C(8)H(3)F(6))(4)], lies on a twofold rotation axis with the Sn(IV) ion in a distorted tetra-hedral coordination environment. Both -CF(3) groups attached to one of the unique benzene rings are disordered over two sets of sites, with the ratios of refined occupancies being 0.719?(14):0.281?(14) and 0.63?(5):0.37?(5).

Tetra-potassium hepta-cyanido-molybdate(III) dihydrate.

Project description:The asymmetric unit of the title compound, K(I) (4)[Mo(III)(CN)(7)]·2H(2)O, consists of one [Mo(CN)(7)](4-) anion, four K(+) cations, and two water mol-ecules. The [Mo(III)(CN)(7)](4-) anion has a seven-coordinated capped-trigonal-prismatic coordination geometry. The site-occupancy factors of the disordered water mol-ecules were set at 0.90, 0.60 and 0.50. The H-atom positions could not be determined for two of the water mol-ecules. The H atoms of the water with a site-occupancy factor of 0.90 were refined using O-H and H⋯H distance restraints.
