1-Benzyl-4-chloro-indoline-2,3-dione.

There are two independent molecules in the asymmetric unit of the title compound, C15H10ClNO2, which differ in the dihedral angles between the mean planes of the phenyl ring and the 4-chloroindoline-2,3-dione ring system [59.48 (9) and 79.0 (1)°]. In the crystal, molecules are linked through C—H⋯O hydrogen bonds, forming polymeric chains in [100].

3-Chloro­azepan-2-one

In the title compound, C6H10ClNO, an intermediate for the production of lysine, there are intramolecular C—H⋯Cl hydrogen bonds.

1-Benzoyl-3-chloro-azepan-2-one.

In the crystal structure of the title compound, C13H14ClNO2, intermolecular C—H⋯O interactions link the molecules into a two-dimensional network.

Di‐μ‐adipato‐κ6O,O′:O′′;O:O′,O′′‐bis[aqua­(1,10‐phenanthroline‐κ2N,N)zinc(II)]

In the title compound, [Zn2(C6H8O4)2(C12H8N2)2(H2O)2], each Zn atom is six-coordinated in the ZnO4N2 form in a distorted tetragonal–bipyramidal geometry. The water molecules act as donors in O—H⋯O hydrogen bonds, connecting the molecules into chains. The packing is further stabilized by intermolecular C—H⋯O interactions.

N-Cyclo­hexyl-N-{[3-(4,6-dimeth­oxy­pyrimidin-2-yl­oxy)pyridin-2-yl]meth­yl}4,6-dimeth­oxy­pyrimidin-2-amine

In the title compound, C24H30N6O5, the cyclohexyl ring adopts a chair conformation, while the remainder of the molecule adopts a U-shape. The dihedral angles between the pyridine ring and the pendant pyrimidine rings are 69.04 (12) and 75.99 (9)°. The two pyrimidine rings, however, are nearly parallel to one another, with a dihedral angle of 8.56 (15)° between them. They are also involved in an intramolecular π–π stacking interaction with a distance of 3.6627 (18) Å between the ring centroids. In the crystal, C—H⋯O contacts link the molecules into chains along the b axis.

[2-(1H-Indol-4-yl)eth­yl]dipropyl­amine

In the title compound, C16H24N2, the aliphatic amine substituent is rotated almost orthogonally [C—C—C—C torsion angle = 75.7 (3)°] out of the plane of the indole unit. The amine N atom has a pyramidal configuration deviating by 0.380 (3) Å from the plane of the adjacent C atoms. All of the aliphatic groups are in extended transoid conformations. In the crystal, molecules form chains along the a axis via N—H⋯N hydrogen bonds.

In the title compound, C13H12N2O4, the dihedral angle between the benzene and pyrimidine rings is 55.57 (13)°. The carbonyl group and the two methoxyl groups are approximately coplanar with the benzene ring and pyrimidine ring; the C—C—C—O, C—O—C—N and C—O—C—C torsion angles being −6.1 (5), −4.8 (4) and 179.9 (3)°, respectively. In the crystal, molecules are linked via C—H⋯O interactions, forming chains propagating along [110].

5-Methyl-N-[2-(trifluoro­meth­yl)phen­yl]isoxazole-4-carboxamide

In the title compound, C12H9F3N2O2, the benzene ring is nearly perpendicular to the isoxazole ring, making a dihedral angle of 82.97 (2)°. In the crystal, molecules are linked by N—H⋯O hydrogen bonds into a supramolecular chain running along the c axis.

In the racemic title compound, C14H17NO6, the plane of the ester group of the methyl hexanoate side chain makes a dihedral angle of 80.0 (2)° with the benzene ring, while the nitro group is approximately coplanar with the benzene ring [dihedral angle = 10.3 (2)°]. In the crystal, molecules form weak aromatic C—H⋯Onitro hydrogen-bonding interactions, giving inversion dimers [graph set R 2 2(8)].
