TL;DR: Two isomorphous molecules lie in mirror planes, with the C(6) rings perpendicular to the mirror, and an aromatic region, with phenyl ring-CN interactions, and the CN ends of the molecules are also involved in a CN.NC dipolar interaction.
Abstract: p-Decylphenyl isocyanide, p-C10H21–C6H4–NC or C17H25N, and p-decylbenzonitrile, p-C10H21–C6H4–CN or C17H25N, are isomorphous. The molecules lie in mirror planes, with the C6 rings perpendicular to the mirror. The packing of both molecules includes an aliphatic region, with close to ideal packing of the C10H21 chains, and an aromatic region, with phenyl ring–CN interactions. In addition, the CN ends of the molecules are also involved in a CN⋯NC dipolar interaction.

TL;DR: In this article, the authors presented a slightly puckered molecular sheets (moles tilted 4.1°(2)° with respect to the sheets) of 2.2,6-Difluorobenzonitrile packs.
Abstract: 2,6-Difluorobenzonitrile packs in slightly puckered molecular sheets (molecules tilted 4.1 (2)° with respect to the sheets). All of the H atoms in the molecule are in contact with N and F atoms in adjacent molecules in the sheet.

TL;DR: In this article, the major component of C8Cl3IN2 is disordered in the crystal and the angle is approximately linear at the halogen atom and bent at the nitro-gen.
Abstract: The molecule of the title compound, C8Cl3IN2, is disordered in the crystal. For the major component, there is an I⋯N intermolecular contact of 3.06 (3) A and two Cl⋯N contacts of 3.10 (3) and 3.19 (3) A. In all three contacts, the angle is approximately linear at the halogen atom and bent at the nitrogen.

TL;DR: The title p-haloacetophenones, C8H7XO (X = Cl, Br and I), have different packing modes, and the bromo compound and one polymorph (A) of the iodo compound are isomorphous, with significant X⋯O contacts.
Abstract: The title p-haloacetophenones, C8H7XO (X = Cl, Br and I), have different packing modes. The chloro compound contains H⋯O and H⋯Cl contacts, but no Cl⋯O contacts. The bromo compound and one polymorph (A) of the iodo compound are isomorphous, with significant X⋯O contacts [Br⋯O = 3.320 (4) A and I⋯O = 3.374 (5) A]. In the other polymorph (B) of the iodo compound, the I⋯O distance is 3.082 (4) A. Both polymorphs contain C—H⋯π contacts; these contacts are shorter in A than in B.

TL;DR: In this article, a 2.847-N distance was achieved by OðH⋯NC hydrogen bonds, with an OðN distance of 2.747 n 2.
Abstract: m-Cyanophenol, NC—C6H4—OH or C7H5NO, crystallizes as chains of molecules held together by O—H⋯NC hydrogen bonds, with an O⋯N distance of 2.847 (2) A.

TL;DR: The 1:1 complex of 4,7-di-bromo-benzo and pyrene, C6H2N2O2Br2·C16H10, contains π stacks of alternating mol-ecules as discussed by the authors.
Abstract: The 1:1 complex of 4,7-dibromobenzo[c]furazan 1-oxide and pyrene, C6H2N2O2Br2·C16H10, contains π stacks of alternating molecules. The molecules are tilted by 2.5 (1)° with respect to each other and by 22.6 (1) and 25.0 (1)°, respectively, away from being normal to the direction of the stack. The average intermolecular distances in the stack alternate between 3.45 (2) and 3.49 (2) A. There are no unusual contacts between adjacent stacks.
