Redetermination of AgPO(3).

ABSTRACT: Single crystals of silver(I) polyphosphate(V), AgPO(3), were prepared via a phospho-ric acid melt method using a solution of Ag(3)PO(4) in H(3)PO(4). In comparison with the previous study based on single-crystal Weissenberg photographs [Jost (1961 ?). Acta Cryst. 14, 779-784], the results were mainly confirmed, but with much higher precision and with all displacement parameters refined anisotropically. The structure is built up from two types of distorted edge- and corner-sharing [AgO(5)] polyhedra, giving rise to multidirectional ribbons, and from two types of PO(4) tetra-hedra linked into meandering chains (PO(3))(n) spreading parallel to the b axis with a repeat unit of four tetra-hedra. The calculated bond-valence sum value of one of the two Ag(I) ions indicates a significant strain of the structure.

Redetermination of MgCrO4·5H2O.

Project description:The CCD-data based redetermination of the crystal structure of the title compound, magnesium chromate(VI) penta-hydrate, confirms in principle the previous study based on precession film data [Bertrand et al. (1971 ?). C. R. Hebd. Seances Acad. Sci. Serie C, 272, 530-533.], but with all atoms refined with anisotropic displacement parameters and with all H atoms localized. This allowed an unambiguous assignment of the hydrogen-bonding pattern. MgCrO4·5H2O adopts the MgSO4·5H2O structure type. It contains two Mg(2+) sites on special positions with site symmetry -1, one tetra-hedral CrO4 group and five water mol-ecules. Four of them coordinate to the Mg(2+) cation, and one is an uncoordinating lattice water mol-ecule. The octa-hedral environment of the Mg(2+) cation is completed by two axial O atoms of CrO4 tetra-hedra. This arrangement leads to the formation of chains parallel to [011]. Adjacent chains are linked through O-H?O hydrogen bonds (one of them bifurcated), involving both the coordi-nating and lattice water mol-ecules, into a three-dimensional network.

Redetermination of loperamide monohydrate.

Project description:The structure of the title compound {systematic name: 4-[4-(4-chloro-phen-yl)-4-hy-droxy-piperidin-1-yl]-N,N-dimethyl-2,2-di-phenyl-butanamide monohydrate}, C(29)H(33)ClN(2)O(2)·H(2)O, has been redetermined at 170?(2)?K. The redetermination is of significantly higher precision than the previous structure determination at room temperature and includes the H-atom coordinates that were not included in the previous report [Germain et al. (1977 ?). Acta Cryst. B33, 942-944]. It consists of a piperidin-1-yl ring in a distorted chair conformation, with the N,N-dimethyl-?,?-diphenyl-butyramide and the 4-chloro-phenyl and hy-droxy groups bonded in para positions and an external water mol-ecule within the asymmetric unit. The dihedral angles between the mean plane of the piperidine ring and the 4-chloro-phenyl and two benzene rings are 83.4?(5), 76.4?(2) and 85.9?(2)°, respectively. The two benzene rings are inclined to one another by 50.8?(6)°. In the crystal, mol-ecules are linked by O-H?O and O-H?N hydrogen bonds and weak C-H?O intermolecular interactions, forming an infinite two-dimensional network along [110].

Redetermination of EuScO(3).

Project description:Single crystals of europium(III) scandate(III), with ideal formula EuScO(3), were grown from the melt using the micro-pulling-down method. The title compound crystallizes in an ortho-rhom-bic distorted perovskite-type structure, where Eu occupies the eightfold coordinated A sites (site symmetry m) and Sc resides on the centres of corner-sharing [ScO(6)] octa-hedra (B sites with site symmetry ). The structure of EuScO(3) has been reported previously based on powder diffraction data [Liferovich & Mitchell (2004). J. Solid State Chem.177, 2188-2197]. The results of the current redetermination based on single-crystal diffraction data shows an improvement in the precision of the structral and geometric parameters and reveals a defect-type structure. Site-occupancy refinements indicate an Eu deficiency on the A site coupled with O defects on one of the two O-atom positions. The crystallochemical formula of the investigated sample may thus be written as (A)(?(0.032)Eu(0.968))(B)ScO(2.952).

Redetermination of 4-hydroxy-benzaldehyde.

Project description:This is a redetermination of the structure of the title compound, C(7)H(6)O(2), which was first reported by Iwasaki [Acta Cryst. (1977 ?), B33, 1646-1648]. The results are obtained with greater precision in the present study. Crystal packing is stabilized by inter-molecular O-H?O inter-actions between the hydroxyl and aldehyde groups which link the mol-ecules into chains in a zigzag pattern along the [110] plane of the unit cell.

Redetermination of 3,5-dimethyl-phenol.

Project description:The previous structure determination [Gillier-Pandraud et al. (1972 ?). C. R. Acad. Sci. Ser. C, 275, 1495] of the title compound, C(8)H(10)O, did not report atomic coordinates. There are two mol-ecules in the asymmetric unit, A and B, which both show approximate non-crystallographic C(s) symmetry. The intra-cyclic C-C-C angles cover the range 118.74?(12)-121.76?(13)°. In the crystal, mol-ecules are linked by O-H?O hydrogen bonds, generating [001] C(2) (2)(4) chains such that mol-ecules A and B alternate. There is no aromatic ?-? stacking in the crystal as the shortest centroid-centroid distance is greater than 4.74?Å.

o-Toluene-sulfonamide: a redetermination.

Project description:The structure of the title compound, C(7)H(9)NO(2)S, was previously determined from powder diffraction data [Tremayne, Seaton & Glidewell (2002). Acta Cryst. B58, 823-834]. It has now been refined to a significantly higher precision. The amino N-atom is bent with a C-C-S-N torsion angle of -65.8?(2)deg;. In the crystal, mol-ecules are packed into a three-dimensional framework/supramolecular structure through hydrogen bonds between the two H atoms of the sulfonamide group and sulfonyl O atoms of neighbouring mol-ecules.

Redetermination of diammonium thio-molybdate.

Project description:In contrast to the previous structure determinations of the title structure, (NH(4))(2)[MoS(4)], the present determination at 173?K localized the positions of the H atoms. The title structure belongs to the ?-K(2)SO(4) family and all the ions are located on crystallographic mirror planes. The ions are held together by N-H?S hydrogen bonds (some of which are bifurcated), forming a three-dimensional network. One of the N atoms has nine contacts to the S atoms shorter than 4?Å, and the other has ten.

Redetermination of 4-nitro-stilbene.

Project description:In the title compound, C(14)H(11)NO(2), the benzene rings are inclined to each other with a dihedral angle between their mean planes of 8.42 (6)°. The nitro group is almost coplanar with the attached benzene ring but is rotated about the C-N bond by 5.84 (12)°. This redetermination results in a crystal structure with significantly higher precision than the original determination [Hertel & Romer (1931 ▶). Z. Kristallogr.76, 467-469], and the intermolecular interactions have been established. In the crystal structure, mol-ecules are linked by C-H⋯O hydrogen bonds to generate C(5), C(13) and edge-fused R(3) (3)(28) rings.

Redetermination of 5-iodo-uracil.

Project description:The title compound (systematic name2,4-dihydr-oxy-5-iodo-pyrimidine), C(4)H(3)IN(2)O(2), which was first reported by Sternglanz, Freeman & Bugg [Acta Cryst. (1975 ▶), B31, 1393-1395], has been redetermined, providing a significant increase in the precision of the derived geometric parameters. The asymmetric unit comprises a non-planar mol-ecule in a slightly distorted B(25) boat conformation. The mol-ecules are associated in the crystal structure to form ribbons stabilized by N-H⋯O hydrogen bonds which involve NH groups and two carbonyl O atoms.

Redetermination of phenyl-hydrazinium chloride.

Project description:In the redetermined structure [Koo (1965 ▶). Bull. Chem. Soc. Jpn, 38, 286] of the title compound, C(6)H(9)N(2) (+)·Cl(-), the H atoms have been located and the hydrogen-bonding scheme established. A series of N-H⋯Cl and N-H⋯N hydrogen bonds leads to a layered network parallel to the (010) plane.
