Crystal structure of (E)-9-(4-nitro­benzyl­idene)-8,9-di­hydro­pyrido[2,3-d]pyrrolo­[1,2-a]pyrimidin-5(7H)-one

The title compound, C17H12N4O3, a pyrido-pyrrolo-pyrimidine derivative, is almost planar. The nitro-benzene ring is inclined to the mean plane of the 8,9-di-hydro-pyrido[2,3-d]pyrrolo-[1,2-a]pyrimidin-5(7H)-one moiety (r.m.s. deviation = 0.023 Å) by 6.8 (1)°. In the crystal, mol-ecules are linked via C-H⋯O and C-H⋯N hydrogen bonds, forming layers parallel to (101).

Crystal structure of (E)-3-(5-bromo-2-hydroxy­phen­yl)acryl­aldehyde

The title compound, C9H7BrO2, displays a trans configuration with respect to the C=C double bond and is essentially planar [maximum deviation from the least-squares plane through all non-H atoms = 0.056 (4) Å]. The vinyl-aldehyde group adopts an extended conformation wih a C-C-C-C torsion angle of 179.7 (4)°. In the crystal, mol-ecules are linked by classical O-H⋯O and weak C-H⋯O hydrogen bonds...

Crystal structure of 2-acetyl-5-(3,4-di­meth­oxy­phen­yl)-6-eth­oxy­carbonyl-3,7-dimethyl-5H-thia­zolo[3,2-a]pyrimidin-8-ium chloride

The title mol-ecular salt, C21H25N2O5S(+)·Cl(-), crystallizes with two ion pairs in the asymmetric unit. The cations have similar conformations (r.m.s. overlay fit = 0.40 Å), with one of them showing disorder of the terminal methyl group of the ester in a 0.72 (2):0.28 (2) ratio. In the first cation, the 3,4-dimeth-oxy-substituted phenyl ring subtends a dihedral angle of 88.38 (7)° with the pyr...
