Crystal structure of (2E)-1-(4-hy-droxy-1-methyl-2-oxo-1,2-di-hydro-quinolin-3-yl)-3-(4-hy-droxy-3-meth-oxy-phen-yl)prop-2-en-1-one.

In the title compound, C20H17NO5, the dihedral angle between the mean plane of the di-hydro-quinoline ring system (r.m.s.

Crystal structure of chlorido-{4,5-dimeth-oxy-2-[(2,3-η)-2-prop-2-en-1-yl]phenyl-κC (1)}(piperidine-κN)platinum(II) ethanol monosolvate.

In the title compound, [Pt(C11H13O2)Cl(C5H11N)]·C2H5OH, the Pt(II) cation is penta-coordinated in a distorted square-planar geometry. In the crystal, inversion dimers showing C-H⋯Cl and C-H⋯π inter-actions are further stacked in columns along the a axis via C-H⋯π inter-actions. The ethanol solvate mol-ecule inter-acts with neighbouring meth-oxy groups of methyl-eugenol through O-H⋯O hydrogen bonds.

Crystal structure of (1Z)-1-(4-chloro-benzyl-idene)-5-(4-meth-oxy-phen-yl)-3-oxopyrazolidin-1-ium-2-ide.

The title mol-ecule, C17H15ClN2O2, is L-shaped with the 4-chloro-benzyl-idene ring almost coplanar with the planar pyrazolidine ring (r.m.s.

N-tert-butyl-N'-[5-cyano-2-(4-methylphenoxy)phenylsulfonyl]urea, a new TXA₂ receptor antagonist.

The title compound, C₁₉H₂₁N₃O₄S, crystallizes in the space group P2/c with two molecules in the asymmetric unit. The conformation of both molecules is very similar and is mainly determined by an intramolecular N-H∙∙∙O hydrogen bond between a urea N atom and a sulfonyl O atom. The O and second N atom of the urea groups are involved in dimer formation via N-H∙∙∙O hydrogen bonds.

Redetermination of bis-{(1S,2S,4S,5R)-2-[(R)-hy-droxy(6-meth-oxy-4-quinol-yl)meth-yl]-5-vinyl-quinuclidinium} sulfate dihydrate.

The structure of the title compound, known as quinine sulfate dihydrate, 2C(20)H(25)N(2)O(2) (+)·SO(4) (2-)·2H(2)O, was previously reported by Mendel [Proc. K. Ned.

Redetermination of {5-[(7-chloro-quinolinium-4-yl)amino]-2-hy-droxy-benz-yl}diethyl-ammonium dichloride dihydrate.

THE STRUCTURE OF THE TITLE COMPOUND (COMMON NAME: amodiaquinium dichloride dihydrate), C(20)H(24)ClN(3)O(2) (+)·2Cl(-)·2H(2)O, was previously determined from powder diffraction data [Llinàs et al. (2006 ▶). Acta Cryst.
