1-Methyl-3,5-bis[(E)-(3-methyl-2-thienyl)methylene]piperidin-4-one monohydrate
In the title mol-ecule, C(18)H(19)NOS(2)·H(2)O, the piperidine ring adopts an envelope conformation with the methyl substituent in an equatorial position. Each of the olefinic double bonds has an E configuration. The dihedral angle between the two thio-phene rings is 6.04 (14)°. The water mol-ecule forms two donor inter-actions, one with the carbonyl O atom and the other to the hetero N atom. T...
متن کامل(2E)-3-(4-Methylphenyl)-1-(2-methyl-4-phenylquinolin-3-yl)prop-2-en-1-one monohydrate
The title hydrate, C(26)H(21)NO·H(2)O, exhibits significant twists of the benzene ring [dihedral angle = 87.24 (6)°] and chalcone residue [C-C-C-C torsion angle = -94.46 (17)°] out of the plane through the quinoline ring system. The conformation about the C=C bond [1.341 (2) Å] is E. The solvent water mol-ecule forms hydrogen bonds to carbonyl O and quinoline N atoms derived from two mol-ecules...
متن کامل(2E)-3-(4-Ethoxyphenyl)-1-(2-methyl-4-phenylquinolin-3-yl)prop-2-en-1-one monohydrate
The title hydrate, C(27)H(23)NO(2)·H(2)O, features an almost planar quinoline residue (r.m.s. deviation = 0.015 Å) with the benzene [dihedral angle = 63.80 (7) °] and chalcone [C-C-C-O torsion angle = -103.38 (18)°] substituents twisted significantly out of its plane. The configuration about the C=C bond [1.340 (2) Å] is E. In the crystal, mol-ecules related by the 2(1) symmetry operation are l...
متن کامل5-Cyclohexyl-4-methyl-1H-pyrazol-3(2H)-one monohydrate
In the title compound, C(10)H(16)N(2)O·H(2)O, the cyclo-hexane ring is in a chair conformation and its least-squares plane makes a dihedral angle of 53.68 (5)° with the approximately planar pyrazole ring [maximum deviation = 0.034 (1) Å]. Pairs of inter-molecular N-H⋯O hydrogen bonds form inversion dimers between neighbouring pyrazolone mol-ecules, generating R(2) (2)(8) ring motifs. The pyrazo...
متن کامل4-Methyl-2,3-dihydro-1H-1,5-benzodiazepin-2-one monohydrate
The seven-membered fused-ring in the title compound, C(10)H(10)N(2)O·H(2)O, adopts a boat conformation (with the two phenyl-ene C atoms representing the stern and the methyl-ene C atom the prow). In the crystal, two benzodiazepinone mol-ecules are linked about a center of inversion by diazepine-carbonyl N-H⋯O hydrogen bonds. The dimers are further linked by water-diazepine O-H⋯N hydrogen bonds,...
