Crystal structure of tris-(ethyl-enedi-ammonium) hexasulfatopraseodymium(III) hexa-hydrate.

ABSTRACT: In the title salt, (C2H10N2)3[Pr2(SO4)6]·6H2O, the Pr(III) cation is surrounded ninefold by five sulfate groups (two monodentate and three chelating) and by one water mol-ecule [range of Pr-O bond lengths 2.383?(3) to 2.582?(3)?Å]. The [Pr(SO4)5(H2O)] groups are arranged in sheets parallel to (010). Two crystal water mol-ecules and two ethyl-enedi-ammonium cations (one with point group symmetry -1) connect the sheets via O-H?O and N-H?O hydrogen bonds from weak up to medium strength into a three-dimensional framework structure.

Tris(piperazine-1,4-diium) bis-[hexa-chloridoindate(III)] tetra-hydrate.

Project description:The asymmetric unit of the title compound, (C(4)H(12)N(2))(3)[InCl(6)](2)·4H(2)O, consists of one and half independent piperazinium cations, an hexa-chloridoindate anion and two mol-ecules of water. The In(III) ion is six-coordinated and forms a quasi-regular octa-hedral arrangement. In the crystal, alternating layers of cations and anions are arranged parallel to (10[Formula: see text]) and are linked with the water mol-ecules via intra- and inter-molecular N-H⋯O, O-H⋯Cl, C-H⋯O and N-H⋯Cl hydrogen bonds, forming a complex three-dimensional network. Additional stabilization within the layers is provided by weak inter-molecular C-H⋯Cl inter-actions.

Ethyl-enedi-ammonium sodium tetra-kis-[bis-(ethyl-enedi-amine-?(2) N,N')(oxalato-?(2) O (1),O (2))cobalt(III)] [penta-hydrogen di(phosphato-octa-deca-tungstate)] tetra-deca-hydrate.

Project description:The title compound, Na(C2H10N2)[Co(C2O4)(C2H8N2)2]4[H5(P2W18O62)2]·14H2O, prepared under hydro-thermal conditions, consists of two Dawson-type [P2W18O62](6-) anions, four isolated [Co(en)2(ox)](+) cations (en = ethyl-enedi-amine and ox = oxalate), one Na(+) cation, one [H2en](2+) cation, and a number of ordered (14) and disordered solvent water mol-ecules. The [P2W18O62](6-) polyoxidometalate anion has site symmetry 1 and contains two structurally distinct types of W atoms: viz. six W atoms on vertical pseudo-mirror planes grouped in two sets of three, and 12 equatorial W atoms that do not lie in the pseudo-mirror planes grouped in two sets of six. In each [Co(en)2(ox)](+) cation, the Co(III) ion is coordinated by four N atoms from two en ligands and two O atoms from the ox ligands, completing a distorted octa-hedral structure. The sodium cation lies on an inversion centre and additionally links the complex cations and anions. In the crystal, the various units are linked by N-H?O and O-H?O hydrogen bonds, which together with C-H?O hydrogen bonds form a three-dimensional structure. The contribution of a region of disordered electron density, possibly highly disordered solvent water mol-ecules, to the scattering was removed with the SQUEEZE option of PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155]. To equilibrate the charges five H(+) ions have been added to the polyoxidometalate. These H(+) ions and the disordered solvent contribution were not included in the reported mol-ecular weight and density.

Tris(1-ethyl-3-methyl-imidazolium) hexa-bromidoeuropate(III).

Project description:The crystal structure of the title compound, (C(6)H(11)N(2))(3)[EuBr(6)], consists of 1-ethyl-3-methyl-imidazolium cations and centrosymmetric octa-hedral hexa-bromido-europate anions. The [EuBr(6)](3-) anions are located at the corners and face-centres of the monoclinic unit cell. Characteristic hydrogen-bonding inter-actions can be observed between the bromide anions and the acidic H atoms of the imidazolium cations.

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.

Tris(ethyl-enedi-amine)-cobalt(II) dichloride.

Project description:The title compound, [Co(II)(C2H8N2)3]Cl2, was obtained unexpectedly as the product of an attempted solvothermal synthesis of cobalt selenide from the elements in the presence of NH4Cl in ethyl-enedi-amine solvent. The three chelate rings of the distorted octa-hedral [Co(C2H8N2)3](2+) complex cation adopt twisted conformations about their C-C bonds. The spread of cis-N-Co-N bond angles [80.17 (6)-98.10 (6)°] in the title compound is considerably greater than the equivalent data for [Co(III)(C2H8N2)3]Cl3 [Takamizawa et al. (2008 ▶). Angew. Chem. Int. Ed. 47, 1689-1692]. In the crystal, the components are linked by numerous N-H⋯Cl hydrogen bonds, generating a three-dimensional network in which the cationic complexes are stacked in columns along [010] and separated by columns of chloride anions.

Hexakis(1H-imidazole-?N)cobalt(III) tris-(hexa-fluoridophosphate) hexa-hydrate.

Project description:In the crystal structure of the title compound, [Co(C(3)H(4)N(2))(6)](PF(6))(3)·6H(2)O, the Co(III) atom lies on a special position with site-symmetry and the P atom is located on a special position with site symmetry . The Co(III) atom has an almost ideal octa-hedral coordination formed by the N atoms of six imidazole ligands. The water mol-ecules form hydrogen-bonded helical chains propagating in [001] by O-H?O inter-actions with a distance of 2.913?(2)?Å. They simultaneously inter-act as hydrogen-bond acceptors and donors with the cations and anions, respectively, resulting in the formation of a three-dimensional assembly. Weak C-H?F inter-actions further stabilize the crystal structure.

Tris[hexa-amminecobalt(III)] bis-[tri-oxalato-cobaltate(II)] chloride dodeca-hydrate.

Project description:The title compound, [Co(III)(NH?)?]?[Co(II)(C?O?)?]?Cl·12H?O, was synthesized under hydro-thermal conditions. The asymmetric unit comprises two [Co(NH?)?]³? cations, one located on a threefold axis and the other on a site of symmetry -3, a [Co(C?O?)?]?? anion, located on a threefold axis, one sixth of a chloride anion [disordered over two sites, one threefold (site occupancy = 0.5) and the other -3 (site occupancy (0.25)] and two water molecules. Both Co(III) centers are six-coordinated by NH? mol-ecules, forming [Co(NH?)?]³? octa-hedra, with Co-N distances in the range 1.958?(2)-1.977?(3)?Å. The title structure gives the first example of the [Co(C?O?)?]?? anion, with the distorted octa-hedral environment of Co(II) center formed by six O atoms from three oxalate residues. The Co-O bond lengths are 2.0817?(18) to 2.0979?(18)?Å. Multiple N-H?O, N-H?Cl and O-H?O hydrogen bonds link the cations, anions and water mol-ecules into a three-dimensional network.

Crystal structure of tris-(hydroxyl-ammonium) orthophosphate.

Project description:The crystal structure of the title salt, ([H3NOH](+))3·[PO4](3-), consists of discrete hydroxyl-ammonium cations and ortho-phos-phate anions. The atoms of the cation occupy general positions, whereas the anion is located on a threefold rotation axis that runs through the phospho-rus atom and one of the phosphate O atoms. In the crystal structure, cations and anions are linked by inter-molecular O-H?O and N-H?O hydrogen bonds into a three-dimensional network. Altogether, one very strong O-H?O, two N-H?O hydrogen bonds of medium strength and two weaker bifurcated N-H?O inter-actions are observed.

Crystal structure of tris-[4-(di-methyl-amino)-pyridinium] tris-(oxalato-?(2) O,O')chromate(III) tetra-hydrate.

Project description:In the title hybrid salt, (C7H11N2)3[Cr(C2O4)3]·4H2O, the central Cr(III) ion of the complex anion (point group symmetry 2) is coordinated by six O atoms from three chelating oxalate(2-) ligands in a slightly distorted octa-hedral coordination sphere. The Cr-O bond lengths vary from 1.9577?(11) to 1.9804?(11)?Å, while the chelate O-Cr-O angles range from 82.11?(6) to 93.41?(5)°. The 4-(di-methyl-amino)-pyridinium cations (one situated in a general position and one on a twofold rotation axis) are protonated at the pyridine N atoms. In the crystal, N-H?O and O-H?O hydrogen bonds link the cations and anions into a three-dimensional network. ?-? inter-actions between the pyridine rings of adjacent cations provide additional stabilization of the crystal packing, with the closest centroid-to-centroid distances being 3.541?(1) and 3.575?(1)?Å.
