Crystal structure of lead(II) tartrate: a redetermination.

ABSTRACT: Single crystals of poly[?4-tartrato-?(6) O (1),O (3):O (1'):O (2),O (4):O (4')-lead], [Pb(C4H4O6)] n , were grown in a gel medium. In comparison with the previous structure determination of this compound from laboratory powder X-ray diffraction data [De Ridder et al. (2002 ?). Acta Cryst. C58, m596-m598], the redetermination on the basis of single-crystal data reveals the absolute structure, all atoms with anisotropic displacement parameters and a much higher accuracy in terms of bond lengths and angles. It could be shown that a different space group or incorporation of water as reported for similarly gel-grown lead tartrate crystals is incorrect. In the structure, each Pb(2+) cation is bonded to eight O atoms of five tartrate anions, while each tartrate anion links four Pb(2+) cations. The resulting three-dimensional framework is stabilized by O-H?O hydrogen bonds between the OH groups of one tartrate anion and the carboxyl-ate O atoms of adjacent anions.

Redetermination of (d-penicillaminato)lead(II).

Project description:In the title coordination polymer, [Pb(C(5)H(9)NO(2)S)](n) {systematic name: catena-poly[(?-2-amino-3-methyl-3-sulfido-butano-ato)lead(II)]}, the d-penicillaminate ligand coordin-ates to the metal ion in an N,S,O-tridentate mode. The S atom acts as a bridge to two neighbouring Pb(II) ions, thereby forming a double thiol-ate chain. Moreover, the coordinating carboxyl-ate O atom forms bridges to the Pb(II) ions in the adjacent chain. The overall coordination sphere of the Pb(II) ion can be described as a highly distorted penta-gonal bipyramid with a void in the equatorial plane between the long Pb-S bonds probably occupied by the stereochemically active inert electron pair. The amino H atoms form N-H?S and N-H?O hydrogen bonds, resulting in a cluster of four complex units, giving rise to an R(4) (4)(16) ring lying in the ab plane. The crystal structure of the title compound has been reported previously [Freeman et al. (1974 ?). Chem. Soc. Chem. Commun. pp. 366-367] but the atomic coordinates have not been deposited in the Cambridge Structural Database (refcode DPENPB). Additional details of the hydrogen bonding are presented here.

Crystal structure of Hg2SO4 - a redetermination.

Project description:The crystal structure of mercury(I) sulfate (or mercurous sulfate), Hg2SO4, was re-determined based on modern CCD data. In comparison with the previous determination from Weissenberg film data [Dorm (1969 ?). Acta Chem. Scand. 23, 1607-1615], all atoms were refined with anisotropic displacement parameters, leading to higher precision in terms of bond lengths and angles [e.g. Hg-Hg = 2.5031?(7) compared to 2.500?(3)Å]. The structure consists of alternating rows along [001] of Hg2 (2+) dumbbells (generated by inversion symmetry) and SO4 (2-) tetra-hedra (symmetry 2). The dumbbells are linked via short O-Hg-Hg-O bonds to the sulfate tetra-hedra into chains extending parallel to [20-1]. More remote O-Hg-Hg-O bonds connect these chains into a three-dimensional framework.

Diterbium hepta-nickel: a crystal structure redetermination.

Project description:The crystal structure of the title compound, Tb2Ni7, was redetermined from single-crystal X-ray diffraction data. In comparison with previous studies based on powder X-ray diffraction data [Lemaire et al. (1967). C. R. Acad. Sci. Ser. B, 265, 1280-1282; Lemaire & Paccard (1969). Bull. Soc. Fr. Mineral. Cristallogr. 92, 9-16; Buschow & van der Goot (1970). J. Less-Common Met. 22, 419-428], the present redetermination affords refined coordinates and anisotropic displacement parameters for all atoms. A partial occupation for one Tb atom results in the non-stoichiometric composition Tb1.962?(4)Ni7. The title compound adopts the Ce2Ni7 structure type and can also be derived from the CaCu5 structure type as an inter-growth structure. The asymmetric unit contains two Tb sites (both site symmetries 3m.) and five Ni sites (.m., mm2, 3m., 3m., -3m.). The two different coordination polyhedra of Tb are a Frank-Kasper polyhedron formed by four Tb and 12 Ni atoms and a pseudo Frank-Kasper polyhedron formed by two Tb and 18 Ni atoms. The four different coordination polyhedra of Ni are Frank-Kasper icosa-hedra formed by five Tb and seven Ni atoms, four Tb and eight Ni atoms, three Tb and nine Ni atoms, and six Tb and six Ni atoms, respectively.

Crystal structure of (S)-sec-butyl-ammonium l-tartrate monohydrate.

Project description:The title hydrated mol-ecular salt, C4H12N+·C4H5O6-·H2O, was prepared by deprotonation of enanti-opure l-tartaric acid with racemic sec-butyl-amine in water. Only one enanti-omer was observed crystallographically, resulting from the combination of (S)-sec-butyl-amine with l-tartaric acid. The sec-butyl-ammonium moiety is disordered over two conformations related by rotation around the CH-CH2 bond; the refined occupancy ratio is 0.68?(1):0.32?(1). In the crystal, mol-ecules are linked through a network of O-H?O and N-H?O hydrogen-bonding inter-actions, between the ammonium H atoms, the tartrate hy-droxy H atoms, and the inter-stitial water, forming a three-dimensional supra-molecular structure.

Crystal structure of K[Hg(SCN)3] - a redetermination.

Project description:The crystal structure of the room-temperature modification of K[Hg(SCN)3], potassium tri-thio-cyanato-mercurate(II), was redetermined based on modern CCD data. In comparison with the previous report [Zhdanov & Sanadze (1952 ?). Zh. Fiz. Khim. 26, 469-478], reliability factors, standard deviations of lattice parameters and atomic coordinates, as well as anisotropic displacement parameters, were revealed for all atoms. The higher precision and accuracy of the model is, for example, reflected by the Hg-S bond lengths of 2.3954?(11), 2.4481?(8) and 2.7653?(6)?Å in comparison with values of 2.24, 2.43 and 2.77?Å. All atoms in the crystal structure are located on mirror planes. The Hg(2+) cation is surrounded by four S atoms in a seesaw shape [S-Hg-S angles range from 94.65?(2) to 154.06?(3)°]. The HgS4 polyhedra share a common S atom, building up chains extending parallel to [010]. All S atoms of the resulting (1) ?[HgS2/1S2/2] chains are also part of SCN(-) anions that link these chains with the K(+) cations into a three-dimensional network. The K-N bond lengths of the distorted KN7 polyhedra lie between 2.926?(2) and 3.051?(3)?Å.

Crystal structure of CdSO4(H2O): a redetermination.

Project description:The crystal structure of the title compound, cadmium sulfate monohydrate or poly[(?2-aqua)(?4-sulfato)-cadmium], was redetermined based on modern CMOS (complementary metal oxide silicon) data. In comparison with the previous study [Bregeault & Herpin (1970 ?). Bull. Soc. Fr. Mineral. Cristallogr. 93, 37-42], all non-H atoms were refined with anisotropic displacement parameters and the hydrogen-bonding pattern unambiguously established due to location of the hydrogen atoms. In addition, a significant improvement in terms of precision and accuracy was achieved. In the crystal, the Cd(2+) cation is coordinated by four O atoms of four sulfate anions and two O atoms of water mol-ecules, forming a distorted octa-hedral trans-[CdO6] polyhedron. Each sulfate anion bridges four Cd(2+) cations and each water mol-ecule bridges two Cd(2+) cations, leading to the formation of a three-dimensional framework, with Cd?Cd separations in the range 4.0757?(2)-6.4462?(3)?Å. O-H?O hydrogen-bonding inter-actions of medium strength between the coordinating water mol-ecules and sulfate anions consolidate the crystal packing.

Redetermination of the crystal structure of NbF4.

Project description:Single crystals of NbF4, niobium(IV) tetra-fluoride, were synthesized by disproportionation of Nb2F5 at 1273?K in a sealed niobium tube, extracted and studied by single-crystal X-ray diffraction. Previous reports on the crystal structure of NbF4 were based on X-ray powder diffraction data and the observed isotypicity to SnF4 [Gortsema & Didchenko (1965 ?). Inorg. Chem. 4, 182-186; Schäfer et al. (1965 ?). J. Less Common Met. 9, 95-104]. The data obtained from a single-crystal X-ray diffraction study meant the atomic coordinates could now be refined as well as their anisotropic displacement parameters, leading to a significant improvement of the structural model of NbF4. In the structure, the Nb atom is octahedron-like surrounded by six F atoms of which four are bridging to other NbF6 octa-hedra, leading to a layer structure extending parallel to the ab plane.

Redetermination of the solvent-free crystal structure of l-proline.

Project description:The title compound, (S)-pyrrolidine-2-carb-oxy-lic acid (C5H9NO2), commonly known as l-proline, crystallized without the inclusion of any solvent or water mol-ecules through the slow diffusion of diethyl ether into a saturated solution of l-proline in ethanol. l-Proline crystallized in its zwitterionic form and the mol-ecules are linked via N-H⋯O hydrogen bonds, resulting in a two-dimensional network. In comparison to the only other publication of a single-crystal structure of l-proline without inclusions [Kayushina & Vainshtein (1965 ▸). Kristallografiya, 10, 833-844], the R1 value is significantly improved (0.039 versus 0.169) and thus, our data provides higher precision structural information.

Crystal structure of 2-bromo-benzoic acid at 120?K: a redetermination.

Project description:The crystal structure of the title compound, C7H5BrO2, was originally studied using photographic data at room temperature with Cu K? radiation [Ferguson & Sim (1962 ?). Acta Cryst. 15, 346-350]. The present study was undertaken at 120?K with a CCD diffractometer using Cu K? radiation, and resulted in improved geometrical parameters. In the mol-ecule, the carb-oxy group is inclined to the benzene ring by 18.7?(2)° and there is a close intra-molecular Br?O contact of 3.009?(3)?Å. In the crystal, mol-ecules are linked by pairs of O-H?O hydrogen bonds, forming inversion dimers with the classical R 2 (2)(8) ring motif for carb-oxy-lic acids. Neighbouring dimers are linked by weak C-H?O hydrogen bonds, forming tapes propagating in [1-10]. Adjacent tapes inter-act by slipped parallel ?-? inter-actions [inter-centroid distance = 3.991?(2), inter-planar distance = 3.509?(2)?Å, slippage = 1.900?Å] to form columns approximately along the b-axis direction. Neighbouring columns inter-act dispersively, forming a three-dimensional framework structure.

Redetermination of the crystal structure of β-zinc molybdate from single-crystal X-ray diffraction data.

Project description:The crystal structure of the β-polymorph of ZnMoO4 was re-determined on the basis of single-crystal X-ray diffraction data. In comparison with previous powder X-ray diffraction studies [Katikaneani & Arunachalam (2005 ▸). Eur. J. Inorg. Chem. pp. 3080-3087; Cavalcante et al. (2013 ▸). Polyhedron, 54, 13-25], all atoms were refined with anisotropic displacement parameters, leading to a higher precision with respect to bond lengths and angles. β-ZnMoO4 adopts the wolframite structure type and is composed of distorted ZnO6 and MoO6 octa-hedra, both with point group symmetry 2. The distortion of the octa-hedra is reflected by variation of bond lengths and angles from 2.002 (3)-2.274 (4) Å, 80.63 (11)-108.8 (2)° for equatorial and 158.4 (2)- 162.81 (14)° for axial angles (ZnO6), and of 1.769 (3)-2.171 (3) Å, 73.39 (16)-104.7 (2), 150.8 (2)-164.89 (15)° (MoO6), respectively. In the crystal structure, the same type of MO6 octa-hedra share edges to built up zigzag chains extending parallel to [001]. The two types of chains are condensed by common vertices into a framework structure. The crystal structure can alternatively be described as derived from a distorted hexa-gonally closed packed arrangement of the O atoms, with Zn and Mo in half of the octa-hedral voids.
