Crystal structure of ethyl 2-[2-(4-methyl­benzo­yl)-5-p-tolyl-1H-imidazol-1-yl]acetate

The crystal structure of ethyl 2-[2-(4-methyl­benzo­yl)-5-p-tolyl-1H-imidazol-1-yl]acetate is stabilized by inter­molecular C—H⋯N and C—H⋯O inter­actions.

Accepted 10 February 2016

Crystal structure of (+)-methyl (E)-3-[(2S,4S,5R)-2-amino-5-hy­droxy­methyl-2-tri­chloro­methyl-1,3-dioxolan-4-yl]-2-methyl­prop-2-enoate

In the title compound, intra­molecular hydrogen bonding between the hy­droxy and amino groups forms an S(7) graph-set motif. In the crystal, an inter­molecular O—H⋯O hydrogen bond connects mol­ecules into a dimer. The dimers are further linked into a sheet structure.

Accepted 10 February 2016

Crystal structure of 2-[(3aS,6R)-3,3,6-tri­methyl-3,3a,4,5,6,7-hexa­hydro-2H-indazol-2-yl]thia­zol-4(5H)-one

The absolute structure of the title compound was determined from the synthetic pathway and by resonant scattering. The compound is a new thia­zolidin-4-one derivative, prepared from (R)-thio­semicarbazone pulegone, and was isolated on crystallization from ethanol as the pure (3aS,6R)-diastereisomer.

Accepted 10 February 2016

Crystal structures of four chiral imine-substituted thio­phene derivatives

Thio­phenes substituted in position 2 and 5 by chiral imine groups display non-crystallographic or crystallographic twofold symmetry.

Accepted 8 February 2016

Crystal structure of 1,2-bis­((benzyl­sulfan­yl){2-[1-(2-hy­droxy­phen­yl)ethyl­idene]hydrazin-1-yl­idene}meth­yl)disulfane

The title mol­ecule consists of two Schiff base moieties, namely two S-benzyl-β-N-(2-hy­droxy­phenyl­ethyl­idene)di­thio­carbazate groups, connected through an S—S single bond. The two moieties are twisted with a dihedral angle of 87.88 (4)° between the S2C=N planes.

Accepted 4 February 2016

Crystal structure of fac-tricarbon­yl(cyclo­hexyl isocyanide-κC)(quinoline-2-carboxyl­ato-κ2N,O)rhenium(I)

The ReI atom in the mol­ecule of the title compound has a distorted C4NO coordination sphere defined by three carbonyl ligands, one chelating quinaldate anion and one isocyanide ligand. As a result of the trans effect of the isocyanide derivative, one Re—CO bond is elongated.

Accepted 3 February 2016

N-(2-Acetamido-2-de­oxy-β-D-gluco­pyranos­yl)-N-(3-azido­prop­yl)-O-methyl­hydroxyl­amine

The structure determination of an oxyamine glycoside confirmed that it was obtained in the ring-closed β-pyran­ose configuration with a 4C1 conformation. The mol­ecules are bound by O—H⋯O(OH) hydrogen bonds, notably in a zigzag C(2) chain along the short b (screw) axis, supplemented with an R_{2}^{2}(12) OHO(carbon­yl) link along the a axis and other C(2) links.

Accepted 2 February 2016

Crystal structure of bis­(2-methyl-1H-imidazol-3-ium) di­hydroxidobis(oxalato-κ2O1,O2)stannate(IV) monohydrate

The SnIV atom in the anion of the title compound is six-coordinated by two OH groups and four O atoms from two chelating oxalate ligands. Several N—H⋯O and O—H⋯O hydrogen bonds involving the stannate dianions, the cations and the water mol­ecules result into a three-dimensional network structure.
