Supramolecular Chains

The piperidone ring in the title compound, C18H19NOS2, is in a distorted half-chair conformation, distorted towards a twisted boat, with the central methylene C atom of the propyl backbone lying 0.606 (2) Å out of the plane defined by the other five atoms (r.m.s. deviation = 0.1197 Å). One of the S-bound phenyl rings is almost perpendicular to the least-squares plane through the piperidone ring, whereas the other is splayed [dihedral angles = 75.97 (6) and 44.21 (7)°, respectively]. The most prominent feature of the crystal packing is the formation of helical supramolecular chains along the b axis sustained by C—H...O interactions. The chains are consolidated into a three-dimensional architecture via C—H...π interactions whereby one S-bound phenyl ring accepts two C—H...π contacts.

In the title compound, C25H26N2O2S2, the central CN2S2atoms are almost coplanar (r.m.s. deviation = 0.0058 Å). One phenyl ring clearly lies to one side of the central plane, while the other is oriented in the plane but splayed. Despite the different relative orientations, the phenyl rings form similar dihedral angles of 64.90 (3) and 70.06 (3)° with the central plane, and 63.28 (4)° with each other. The benzene ring is twisted with respect to the central plane, forming a dihedral angle of 13.17 (7)°. The S2C=N, N—N and N—N=C bond lengths of 1.2919 (19), 1.4037 (17) and 1.2892 (19) Å, respectively, suggest limited conjugation over these atoms; the configuration about the N—N=C bond isE. An intramolecular O—H...N hydrogen bond is noted. In the crystal, phenyl–methoxy C—H...O and phenyl–phenyl C—H...π interactions lead to supramolecular double chains parallel to thebaxis. These are connected into a layerviamethyl–phenyl C—H...π interactions, and layers stack along theaaxis, being connected by weak π–π interactions between phenyl rings [inter-centroid distance = 3.9915 (9) Å] so that a three-dimensional architecture ensues.

The title compound, C13H14NO2F3, crystallises with two molecules,AandB, in the asymmetric unit, with similar conformations. The dihedral angles between the piperidine and phenyl rings are 83.76 (2) and 75.23 (2)° in moleculesAandB, respectively. The bond-angle sums around the N atoms [359.1 and 359.7° for moleculesAandB, respectively] indicatesp2hybridization for these atoms. In the crystal, O—H...O hydrogen bonds link the molecules into separate [100] chains ofAandBmolecules. The chains are cross-linked by C—H...O interactions, generating alternating (001) sheets ofAandBmolecules.

The central imidazole ring of the title compound, C24H20Cl2N2O, is twisted with respect to with the planes of the 2,6-dichlorobenzene and two phenyl rings, making dihedral angles of 74.06 (18), 28.52 (17) and 67.65 (18)°, respectively. The phenyl ring not adjacent to the N-bonded 2-hydroxypropyl group shows the greatest twist, presumably to minimize steric interactions. In the crystal, molecules are linked by O—H...N and C—H...O hydrogen-bond contacts into chains along thea-axis direction. The series of parallel chains form a two-dimensional sheet approximately parallel to thebcdiagonal. In addition, C—H...π interactions are observed between the sheets. The atoms of the 2-hydroxypropyl group and the N atom of the 1H-imidazole ring to which it is bonded are disordered over two sets of sites, with an occupancy ratio of 0.722 (5):0.278 (5). The structure was refined as an inversion twin.

In the title compound, C16H16N2O2, the N′-acetylacetohydrazide group is approximately planar (r.m.s. deviation = 0.018 Å for the eight non-H atoms) and makes dihedral angles of 81.92 (6) and 65.19 (6)° with the terminal phenyl rings. The phenyl rings form a dihedral angle of 62.60 (7)°. In the crystal, molecules are linked into sheets lying parallel to (001) by N—H...O and C—H...O hydrogen bonds. One O atom accepts one N—H...O and one C—H...O hydrogen bond and the other O atom accepts one N—H...O and two C—H...O hydrogen bonds. The N—H...O hydrogen bonds lead to R 2 2(8) loops and the C—H...O hydrogen bonds generate R 2 1(6) loops.
