7-Hy-droxy-1,2,3,4-tetra-hydro-quinolin-2-one dihydrate.

ABSTRACT: The asymmetric unit of the title compound, C(9)H(9)NO(2)·2H(2)O, comprises two independent organic mol-ecules and four water mol-ecules of crystallization. The heterocyclic rings are not planar: in one mol-ecule, the C atom bearing the O atom and the adjacent methyl-ene C atom are displaced by 0.320?(3) and 0.677?(3)?Å, respectively, from the other eight atoms of the fused ring system. Equivalent values of 0.243?(3) and 0.659?(3)?Å apply to the second mol-ecule. In the crystal, the components are linked by N-H?O and O-H?O hydrogen bonds, forming a three-dimensional network.

Crystal structure of 3-hy-droxy-methyl-1,2,3,4-tetra-hydro-isoquinolin-1-one.

Project description:In the title compound, C10H11NO2, two independent but virtually superimposable mol-ecules, A and B, comprise the asymmetric unit. The heterocyclic ring in each mol-ecule has a screw-boat conformation, and the methyl-hydroxyl group occupies a position to one side of this ring with N-C-C-O torsion angles of -55.30 (15) (mol-ecule A) and -55.94 (16)° (mol-ecule B). In the crystal, O-H⋯O and N-H⋯O hydrogen bonding leads to 11-membered {⋯HNCO⋯HO⋯HNC2O} heterosynthons, involving three different mol-ecules, which are edge-shared to generate a supra-molecular chain along the a axis. Inter-actions of the type C-H⋯O provide additional stability to the chains, and link these into a three-dimensional architecture.

5-Acetyl-4-(3-hy-droxy-phen-yl)-6-methyl-1,2,3,4-tetra-hydro-pyrimidin-2-one-tris-(hy-droxy-meth-yl)ammonium chloride (2/1).

Project description:The asymmetric unit of the title compound, 2C13H14N2O3·C3H10NO3 (+)·Cl(-), contains two independent mol-ecules (A and B) of the title pyrimidine derivative and one ion-pair of tris-(hy-droxy-meth-yl)ammonium chloride. The pyrimidine ring in each pyrimidine derivative has a half-chair conformation. Its mean plane is inclined to the benzene ring by 87.2?(3)° in mol-ecule A and 85.7?(2)° in mol-ecule B. In the crystal, the pyrimidine derivatives are connected to each other by N-H?O hydrogen bonds, forming chains propagating along the b-axis direction. The chains are linked via O-H-Cl hydrogen bonds, forming corrugated sheets lying parallel to the bc plane. The sheets are linked via C-H?O hydrogen bonds, forming a three-dimensional framework. The tris-(hy-droxy-meth-yl)ammonium chloride mol-ecules are located in the cages of the framework. There are also further C-H?O hydrogen bonds and C-H?? inter-actions present in the three-dimensional framework structure. Both the cation and chloride anion of the tris-(hy-droxy-meth-yl)ammonium chloride ion pair are disordered over two positions, with a refined occupancy ratio of 0.418?(8):0.582?(8) for the cation and 0.71?(4):0.29?(4) for the anion.

Project description:The stereochemistry and regioschemistry (exo) of the title compound, C15H18O5, were determined by the X-ray analysis.

In the crystal, O-H?O hydrogen bonds and weak C-H?O hydrogen bonds link the mol-ecules, forming chains of R 2 (1)(8) rings along [010].

Penta-potassium ?-arsenato-bis-(hy-droxy-tetra-molybdate) dihydrate.

Project description:The title arsenatomolybdate, K(5)[Mo(8)O(24)(OH)(2)(AsO(4))]·2H(2)O, which was obtained hydro-thermally, features an [AsMo(8)O(28)(OH)(2)](5-) anion, which is formed by two Mo(4)O(14)(OH) units that are linked by As in a sandwich-like fashion. The overall symmetry of the anion is m2m. The {Mo(4)O(14)(OH)} core is composed of two pairs of confacial biocta-hedral {Mo(2)O(9)} units with two ?(4)-O atoms which have been characterized as hydroxyl groups. The anions are further inter-connected by potassium cations, forming a three-dimensional network structure with the uncoordinated water mol-ecules occupying the channels. The structure is further stabilized by O-H?O hydrogen bonding.

(8aR,9R)-9-Hy-droxy-7,8,8a,9-tetra-hydro-furo[3,2-f]indolizin-6(4H)-one.

Project description:The title compound, C(10)H(11)NO(3), crystallizes with four independent mol-ecules in the asymmetric unit. Their geometries are very similar and corresponding bond distances are almost identical. The central six-membered ring of the indolizine moiety adopts a envelope conformation [the displacement of the flap atom (the C atom opposite the N atom) being 0.539?(2), 0.548?(3), 0.509?(3) and 0.544?(3)?Å in the four molecules], while the conformation of the oxopyrrolidine ring is close to that of a flat envelope. The displacements of the non-fused C atom opposite the C=O group of the pyrrolidine ring of the four mol-ecules are 0.366?(3), 0.335?(3), 0.173?(3) and -0.310?(3)?Å. In the crystal, O-H?O hydrogen bonds link the mol-ecules into chains, which run parallel to the c axis. The absolute configuration was assigned from the synthesis.
