The title compound, C 24 H 18 FNO 3 , crystallizes in the monoclinic centrosymmetric space group P2 1 /n and its mol-ecular conformation is stabilized via C-H⋯O intra-molecular inter-actions. The supra-molecular network mainly comprises C-H⋯O, C-H⋯F and C-H⋯π inter-actions, which contribute towards the formation of the crystal structure. The different inter-molecular inter-actions have been further analysed via Hirshfeld surface analysis and fingerprint plots., (© Hasija et al. 2020.)

In the title 1:1 cocrystal, C 7 H 4 ClNO 4 ·C 6 H 6 N 2 O, nicotinamide (NIC) and 2-chloro-5-nitro-benzoic acid (CNBA) cocrystallize with one mol-ecule each of NIC and CNBA in the asymmetric unit. In this structure, CNBA and NIC form hydrogen bonds through O-H⋯N, N-H⋯O and C-H⋯O inter-actions along with N-H⋯O dimer hydrogen bonds of NIC. Further additional weak π-π inter-actions stabilize the mol-ecular assembly of this cocrystal., (© Bairagi et al. 2019.)

The title compound, C 15 H 13 N 3 O 2 S, crystallizes in the monoclinic space group P 2 1 / n and its mol-ecular conformation is stabilized via intra-molecular C-H⋯O and C-H⋯N contacts. The supra-molecular structure is mainly governed by C-H⋯N hydrogen-bonded centrosymmetric dimers, C-H⋯O and C-H⋯S hydrogen bonds and S⋯π and π-π stacking inter-actions which, together, lead to the formation of a layered crystal packing. The inter-molecular inter-actions were further evaluated through the mol-ecular electrostatic potential map and Hirshfeld fingerprint analysis.

The title compounds, 2-iodo-benzamide, C 7 H 6 INO (I), and 2-iodo- N -phenyl-benzamide, C 13 H 10 INO (II), were both synthesized from 2-iodo-benzoic acid. In the crystal structure of (I), N-H⋯O and hydrogen bonds form two sets of closed rings, generating dimers and tetra-mers. These combine with C-I⋯π(ring) halogen bonds to form sheets of mol-ecules in the bc plane. For (II), N-H⋯O hydrogen bonds form chains along the a -axis direction, while inversion-related C-I⋯π(ring) contacts supported by C-H⋯π(ring) interactions generate sheets of mol-ecules along the ab diagonal.
