Cover illustration: The molecular structure of 2,7-diethoxy-1,8-bis(4-nitrobenzoyl)naphthalene possesses crystallographically imposed twofold symmetry with two C atoms lying on the rotation axis. The crystal packing is characterized by C-HO=C hydrogen bonds between the benzene rings and the carbonyl groups and C-H
O=N hydrogen bonds between the benzene rings and the nitro groups. See: Mohri, Ohisa, Noguchi, Yonezawa & Okamoto [Acta Cryst. (2014). E70, 138-141].

The structure of a TEMPO derivative with a propynyloxy substituent at the 4-position of the piperidine ring is reported. The crystal packing features an unusual C—H⋯π interaction involving the triple bond of the propyne group which combines with C—H⋯O hydrogen bonds to stack the molecules along the b-axis direction.

The title compound possesses crystallographically imposed twofold symmetry with two C atoms lying on the rotation axis and has a non-coplanarly accumulated aromatic-rings structure. In the crystal, C—H⋯O=C hydrogen bonds between the benzene rings and the carbonyl groups and C—H⋯O=N hydrogen bonds between the benzene rings and the nitro groups are observed; these C—H⋯O hydrogen bonds link the molecules, forming a three-dimensional structure.

In this CdII complex incorporating two monodentate acetate groups and two N,N′-chelating pyridine-2-carboxamide oxime ligands, molecules are assembled into chains along the c axis via N—H⋯O hydrogen bonding. The resulting chains are further assembled by ethanol solvent molecules into a three-dimensional supermolecular structure.

In the title compound, the 1,2,3,4-tetrahydropyridine ring of the quinoline moiety adopts a half-chair conformation while the pyrrolidine ring has an envelope conformation. In the crystal, molecules are linked by N—H⋯O and C—H⋯O hydrogen bonds, forming sheets lying parallel to (10
), which are linked via C—H⋯F hydrogen bonds and C—H⋯π interactions, forming a three-dimensional structure.

A distinctive feature of the crystal structure is the geometry of the dtba moiety, which appears to be stretched and acts as an hydrogen-bonding connector, forming linear chains along [-211] with the 4,4′-bpy moiety by way of O—H⋯N hydrogen bonds and C—H⋯O interactions. The influence of the molecular shape on the hydrogen-bonding pattern is analysed by comparing the title compound and two other 4,4′-bpy co-crystals, showing the way in which this correlates with the packing arrangement.
