N-(1,3-Dioxo-2,3-dihydro-1H-isoindol-2-yl)-4,4′′-difluoro-5′-hy­droxy-1,1′:3′,1′′-terphenyl-4′-carboxamide

The asymmetric unit of the title compound, C₂₇H₁₆F₂N₂O₄, consists of two crystallographically independent mol­ecules (A and B). In mol­ecule B, the isoindoline-1,3-dione ring system is disordered over two set of sites with a site-occupancy ratio of 0.658 (12):0.342 (12). In mol­ecule A, the fluoro-substituted benzene rings make dihedral angles of 18.36 (8) and 46.37 (8)° with the central benzene ring, whereas the corresponding angles are 40.90 (8) and 52.89 (9)° in mol­ecule B. The isoindoline ring system in mol­ecule A and the major and minor components of the disordered isoindoline ring system in mol­ecule B make dihedral angles of 58.50 (4), 54.13 (16) and 70.01 (28) °, respectively, with their attached benzene rings, linked through the amide group. An intra­molecular O—H...O hydrogen bond generates an S(6) ring in each mol­ecule. In the crystal, mol­ecules are linked by N—H...O, C—H...F and C—H...O hydrogen bonds into sheets lying parallel to the bc plane. The crystal studied was a non-merohedral twin with a refined twin component ratio of 0.9316 (8):0.0684 (8).

2,3,5-Triphenyl-2H-tetra­zol-3-ium iodide

The asymmetric unit of the title mol­ecular salt, C₁₉H₁₅N₄⁺·I⁻, contains four 2,3,5-triphenyl-2H-tetra­zol-3-ium cations and five iodide anions, with two of the latter lying on crystallographic inversion centres. In each cation, the tetra­zole ring is essentially planar (r.m.s. deviations = 0.004–0.007 Å). The dihedral angles between the tetra­zole ring and its three attached benzene rings in the four independent cations are: 12.9 (4), 67.0 (4), 48.1 (4); 20.8 (4), 51.1 (4), 62.3 (4); 11.4 (4), 52.3 (4), 47.3 (4) and 6.0 (4), 85.7 (4), 43.5 (4)°. A C—H...I hydrogen bond and C—H...π inter­actions are observed in the crystal.

N-[(4-Chloro­phen­yl)sulfon­yl]acetamide

The asymmetric unit of the title compound, C₈H₈ClNO₃S, consists of two crystallographically independent mol­ecules (A and B). The dihedral angles between the benzene ring and amide C—C(=O)—NH– plane are 87.6 (3) (mol­ecule A) and 86.0 (3)° (mol­ecule B). In the crystal, the independent mol­ecules are alternately linked by N—H...O hydrogen bonds into an infinite chain along the b axis. Short inter­molecular Cl...Cl contacts [3.2882 (5) and 3.2812 (5) Å] are also observed.

5-(4-Bromo­phen­yl)-3-(4-fluoro­phen­yl)-1-phenyl-4,5-dihydro-1H-pyrazole

In the title compound, C₂₁H₁₆BrFN₂, the fluoro-substituted benzene ring is disordered over two orientations about the C—F bond and the C—C bond between the benzene and pyrazole groups with a site-occupancy ratio of 0.516 (8):0.484 (8). The central pyrazole ring [maximum deviation = 0.035 (3) Å] makes dihedral angles of 22.4 (2), 11.0 (2), 77.19 (16) and 7.44 (17)° with the two disorder components of the benzene ring, the bromo-substituted benzene ring and the phenyl ring, respectively. In the crystal, mol­ecules are linked into a layer parallel to the bc plane through C—H...π inter­actions.
