Tris{aqua-bis[3-(2-pyrid-yl)-1H-pyrazole]copper(II)} di-?(9)-arsenato-hexa-triaconta-?(2)-oxido-octa-deca-oxidoocta-deca-molybdate(VI).

ABSTRACT: The title compound, [Cu(C(8)H(7)N(3))(2)(H(2)O)](3)[As(2)Mo(18)O(62)], consists of two subunits, viz. an ?-Dawson-type [As(2)Mo(18)O(62)](6-) anion and a complex [Cu(C(8)H(7)N(3))(2)(H(2)O)](2+) cation. The copper(II) ion (site symmetry .2) is penta-coordinated in a distorted square-pyramidal manner by four N atoms from two chelating 3-(2-pyrid-yl)pyrazole ligands in equatorial positions and one water mol-ecule in the apical position. In the heteropolyanion, two O atoms of the AsO(4) group (3. symmetry) are equally disordered about the threefold rotation axis. N-H?O and O-H?O hydrogen bonding between the neutral mol-ecules and the water mol-ecules leads to a consolidation of the structure.

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.

Tris[(1,4,7,10,13,16-hexa-oxacyclo-octa-deca-ne)rubidium] heptaantimonide-ammonia (1/4).

Project description:The crystal structure of the title compound, [Rb(C(12)H(24)O(6))](3)[Sb(7)]·4NH(3), fills the gap between the already known Zintl anion ammoniates {[Cs(18-crown-6)](3)Sb(7)}(2)·9NH(3) [Wiesler (2007 ▶). Dissertation, Universität Regensburg, Germany] and [K(18-crown-6)](3)Sb(7)·4NH(3) [Hanauer (2007 ▶). Dissertation, Universität Regensburg, Germany]. As in the two known compounds, the anti-mony cage anion in this crystal structure is coordinated by three alkali cations. The coordination spheres of each of the cations are saturated by 18-crown-6 mol-ecules. The ammonia mol-ecules of crystallization are situated between the crown ethers. The neutral, mol-ecular [Rb(18-crown-6)](3)Sb(7) units are inter-connected by multiple dipole-dipole interactions between ammonia and 18-crown-6.

Octa-kis(dimethyl sulfoxide-?O)cerium(III) ?(6)-oxido-dodeca-?(2)-oxido-hexa-oxidohexa-molybdate(VI) dimethyl sulfoxide tetrasolvate.

Project description:The title complex, [Ce(C(2)H(6)OS)(8)](2)[Mo(6)O(19)](3)·4C(2)H(6)OS, was obtained as a byproduct of the reaction of [(C(4)H(9))(4)N](2)[Mo(6)O(19)] with Ce(NO(3))(3)·6H(2)O and phthalic acid in dimethyl-sulfoxide solution. The asymmetric unit consists of a complex [Ce(C(2)H(6)OS)(8)](3+) cation, one and a half of the Lindqvist-type [Mo(6)O(19)](2-) polyanions and two dimethyl-sulfoxide solvent mol-ecules; the half polyanion lies on an inversion center. The Ce(3+) ion is coordinated by eight dimethyl-sulfoxide ligands through the O atoms in the form of a distorted square antiprism. The Ce-O bond lengths range from 2.429?(6) to 2.550?(5)?Å. The cohesion of the structure is ensured by S?O [3.115?(6), 3.242?(10) and 3.12?(3)?Å], O?O [3.037?(10)?Å] and C-H?O inter-actions between cations and anions. The S and C atoms of a dmso ligand are disordered over three sites in a 0.45:0.30:0.25 ratio. The dimethyl-sulfoxide solvent mol-ecules are highly disordered and could not be modelled successfully; their contribution was therefore removed from the refinement using the SQUEEZE routine in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155]. Potential solvent-accessible voids of 500.0?Å(3) occur in the crystal structure.

Poly[[hexa-aqua-tris-[?(2)-2,5-dihy-droxy-1,4-benzoquinona-to(2-)]diholmium(III)] octa-deca-hydrate].

Project description:In the polymeric title compound, {[Ho(2)(C(6)H(2)O(4))(3)(H(2)O)(6)]·18H(2)O}(n), the Ho(III) ion is nine-coordinated by six O atoms derived from three bidentate 2,5-dihy-droxy-1,4-benzoquinonate (DHBQ(2-)) ligands and three O atoms from three water mol-ecules. The Ho(III) ions are connected via three ligands, resulting in the formation of a two-dimensional honeycomb layer parallel to the ab plane. The layer is racemic in which ?- and ?-coordination geometries around Ho(III) ions are alternately arranged. The asymmetric unit comprises a third of a Ho(III) ion, located on a threefold axis, one-half of a DHBQ(2-) ion, located on a centre of inversion, one coordinated water mol-ecule and three uncoordinated water mol-ecules.

Bis{tris-[3-(2-pyrid-yl)-1H-pyrazole]iron(II)} tetra-deca-molybdo(V,VI)silicate.

Project description:The asymmetric unit of the title compound, [Fe(C(8)H(7)N(3))(3)](2)[SiMo(14)O(44)], consists of a complex [Fe(C(8)H(7)N(3))(3)](2+) cation and half of a derivative of an α-Keggin-type anion, [SiMo(14)O(44)](4-). In the mixed-valent Mo(V/VI) anion, the α-Keggin type core is capped on two oppositely disposed tetra-gonal faces by additional (MoO(2)) units. The [SiMo(14)O(44)](4-) anion shows disorder. Two O atoms of the central SiO(4) group ( symmetry) are equally disordered about an inversion centre. Moreover, two of the outer bridging O atoms and the O atoms of the capping (MoO(2)) unit are likewise disordered. The Fe(2+) cation is surrounded in a slightly distorted octa-hedral coordination by six N atoms from three 3-(2-pyrid-yl)-1H-pyrazole ligands. N-H⋯O hydrogen bonding between the cations and anions leads to a consolidation of the structure.

Crystal structure of poly[[hexa-aqua-tris-(?-3,6-di-oxo-cyclo-hexa-1,4-diene-1,4-diolato)dierbium(III)] octa-deca-hydrate].

Project description:The title lanthanide complex, [Er2(C6H2O4)3(H2O)6]·18H2O, is isostructural with its La, Gd, Yb and Lu analogues. The Er3+ ion, located on a threefold rotation axis, is nine-coordinated in a distorted tricapped trigonal-prismatic geometry, which is completed by six oxygen atoms from three dhbq2- ligands and three oxygen atoms from coordinated water mol-ecules. Each dhbq2- ligand acts in a ?2-bis-(bidentate) bridging mode to connect two Er3+ ions to form honeycomb (6,3) two-dimensional sheets extending in the ab plane, having an Er?Er separation of 8.7261?(2)?Å. In the crystal, extensive O-H?O hydrogen-bonding inter-actions involving the coordinated water mol-ecules and the water mol-ecules of crystallization, as well as the oxygen atoms of the dhbq2- ligands, generate an overall three-dimensional supra-molecular network.

Hexa-?(2)-acetato-?O:O'-?(3)-oxido-tris-[aqua-chromium(III)] nitrate acetic acid solvate.

Project description:In the crystal structure of the title salt, [Cr(3)(C(2)H(3)O(2))(6)O(H(2)O)(3)]NO(3)·CH(3)CO(2)H, the trinuclear [Cr(3)(CH(3)CO(2))(6)O(H(2)O)(3)] cluster cation has an oxide O atom that is connected to three water-coordinated Cr(III) atoms, the three metal atoms forming the points of an equilateral triangle. Each of the six acetate carboxyl-ate groups bridges a Cr-O-Cr fragment. The cluster cation inter-acts with the nitrate counter-ion and solvent mol-ecules through O-H?O hydrogen bonds, forming a three-dimensional hydrogen-bonded network.

Tris(4,4'-di-tert-butyl-2,2'-bipyridine-?N,N')molybdenum(II) ?(6)-oxido-dodeca-?(2)-oxido-hexa-oxidohexa-molybdate(VI) acetonitrile tetra-solvate.

Project description:The asymmetric unit of the title compound, [Mo(C(18)H(24)N(2))(3)][Mo(6)O(19)]·4CH(3)CN, comprises an [Mo(di-t-Bu-bipy)(3)](2+) cation (di-t-Bu-bipy is 4,4'-di-tert-butyl-2,2'-bipyridine), two halves of Lindqvist-type [Mo(6)O(19)](2-) anions (with each anion completed by the application of a center of inversion) and four acetonitrile solvent mol-ecules. The geometry around the metal atom of the cation resembles a distorted octa-hedron, with each of the three di-t-Bu-bipy ligands being almost planar [deviation from planarity < 6.3?(2)°]. Supra-molecular inter-actions, namely Mo=O??, C N??, C-H?O and C-H?N, along with electrostatic forces, mediate the crystal packing. Two of the tert-butyl groups are affected by rotational disorder which was modeled over two distinct positions with major site occupancies of 0.707?(9) and 0.769?(8).

Bis{tris-[3-(2-pyrid-yl)-1H-pyrazole]cadmium(II)} dodeca-molybdo(V,VI)phosphate hexa-hydrate.

Project description:The hydro-thermally prepared title compound, [Cd(C(8)H(7)N(3))(3)](2)[PMo(12)O(40)]·6H(2)O, is isotypic with its Mn(II) analogue [Hao et al. (2010 ?). Acta Cryst. E66, m231-m232]. The Cd(II) cation is in a distorted octa-hedral environment, coordinated by six N atoms from three chelating 3-(2-pyrid-yl)-1H-pyrazole ligands. In the reduced heteropolyanion, two O atoms of the central PO(4) group ( symmetry) are equally disordered about an inversion centre. N-H?O and O-H?O hydrogen bonds contribute to the crystal packing. Compared with the Mn(II) analogue, the Cd-N bond lengths are longer at 2.316?(7)-2.334?(6)?Å, versus 2.224?(6)-2.283?(5)?Å for Mn-N, whereas all other bond lengths and angles and the hydrogen-bonding motifs are very similar in the two structures.

Bis{tris-[3-(2-pyrid-yl)-1H-pyrazole]iron(II)} dodeca-molybdo(V,VI)phosphate hexa-hydrate.

Project description:Crystals of the title compound, [Fe(C(8)H(7)N(3))(3)](2)[PMo(12)O(40)]·6H(2)O, prepared under hydro-thermal conditions, are isotypic with the Mn(2+) and Cd(2+) analogues. The Fe(2+) cation is in a distorted octa-hedral coordination by six N atoms from three chelating 3-(2-pyrid-yl)-1H-pyrazole ligands. The heteropoly-anion [PMo(12)O(40)](4-) is a one-electron reduced species in which two O atoms of the central PO(4) group ( symmetry) are equally disordered about an inversion centre. N-H?O and O-H?O hydrogen bonds make a contribution to the crystal packing. The Fe-N bond lengths [2.085?(19)-2.15?(2)?Å] are somewhat shorter than the Mn-N and Cd-N bond lengths [2.224?(6)-2.283?(5) and 2.316?(7)-2.334?(6)?Å, respectively]. All other bond lengths and angles and the hydrogen-bonding motifs are very similar in the isotypic structures.
