Acta Crystallogr E Crystallogr Commun 2024; 80:325-329. [PMID: 38456056 PMCID: PMC10915664 DOI: 10.1107/s2056989024001658] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Accepted: 02/19/2024] [Indexed: 03/09/2024]
Abstract
In the title compound, C21H15N5OS2, mol-ecular pairs are linked by N-H⋯N hydrogen bonds along the c-axis direction and C-H⋯S and C-H⋯O hydrogen bonds along the b-axis direction, with R 2 2(12) and R 2 2(16) motifs, respectively, thus forming layers parallel to the (10) plane. In addition, C=S⋯π and C≡N⋯π inter-actions between the layers ensure crystal cohesion. The Hirshfeld surface analysis indicates that the major contributions to the crystal packing are H⋯H (43.0%), C⋯H/H⋯C (16.9%), N⋯H/H⋯N (11.3%) and S⋯H/H⋯S (10.9%) inter-actions.

Abstract
In the ten-membered 1,3,4,6-tetra-hydro-2H-pyrido[1,2-a]pyrimidine ring system of the title compound, C17H15N5, the 1,2-di-hydro-pyridine ring is essentially planar (r.m.s. deviation = 0.001 Å), while the 1,3-diazinane ring has a distorted twist-boat conformation. In the crystal, mol-ecules are linked by N-H⋯N and C-H⋯N hydrogen bonds, forming a three-dimensional network. In addition, C-H⋯π inter-actions form layers parallel to the (100) plane. Thus, crystal-structure cohesion is ensured. According to a Hirshfeld surface study, H⋯H (40.4%), N⋯H/H⋯N (28.6%) and C⋯H/H⋯C (24.1%) inter-actions are the most important contributors to the crystal packing.

Abstract
In the crystal of the title compound, C6H9ClN2O, mol-ecular pairs form dimers with an R 2 2(8) motif through N-H⋯O hydrogen bonds. These dimers are connect into ribbons parallel to the (100) plane with R 4 4(10) motifs by N-H⋯O hydrogen bonds along the c-axis direction. In addition, π-π [centroid-to-centroid distance = 3.4635 (9) Å] and C-Cl⋯π inter-actions between the ribbons form layers parallel to the (100) plane. The three-dimensional consolidation of the crystal structure is also ensured by Cl⋯H and Cl⋯Cl inter-actions between these layers. According to a Hirshfeld surface study, H⋯H (43.3%), Cl⋯H/H⋯Cl (22.1%) and O⋯H/H⋯O (18.7%) inter-actions are the most significant contributors to the crystal packing.

Abstract
In the title compound, C32H29N5O2·C3H7NO, the bi-cyclo[3.3.1]nonane ring sys-tem adopts a half-chair/twist-boat conformation, with the phenyl rings in equatorial orientations with respect to the piperidine ring. The two oxane rings of the 2-oxabi-cyclo-[2.2.2]octane ring system exhibit a distorted boat conformation. Inter-molecular C-H⋯O and C-H⋯N hydrogen bonds connect the mol-ecules in the crystal, generating layers extending parallel to (100). These layers are connected by C-H⋯π inter-actions. A Hirshfeld surface analysis was per-formed to qu-antify the contributions of the different inter-molecular inter-actions, indicating that the most important contributions to the crystal packing are from H⋯H (52.5%), N⋯H/H⋯N (19.2%), C⋯H/H⋯C (18.8%) and O⋯H/H⋯O (8.3%) inter-actions.

Abstract
The crystal used for structure determination contained, along with the title compound, C17H14BrN3O4, an admixture [0.0324 (11)] of its 7-bromo isomer. The 2,3-di-hydro-1H-indole ring system is nearly planar, while the conformation of the 4H-pyran ring is close to a flattened boat. The mean planes of these fragments form a dihedral angle of 86.67 (9)°. The carboxyl-ate group lies near the plane of 4H-pyran, its orientation is stabilized by an intra-molecular C-H⋯O contact. In the crystal, the mol-ecules are connected into layers by N-H⋯N and N-H⋯O hydrogen bonds. The most important contributions to the crystal packing are from H⋯H (33.1%), O⋯H/H⋯O (16.3%), N⋯H/H⋯N (12.1%), Br⋯H/H⋯Br (11.5%) and C⋯H/H⋯C (10.6%) inter-actions.

The dimers are connected by N-H⋯Br and O-H⋯O hydrogen bonds, and C-Br⋯π inter-actions, forming layers parallel to the (010) plane. 1,6-Di-amino-2-oxo-4-phenyl-1,2-di-hydro-pyridine-3,5-dicarbo-nitrile, C13H9N5O, (II), crystallizes in the triclinic space group P with two independent mol-ecules (IIA and IIB) in the asymmetric unit. In the crystal of (II), mol-ecules IIA and IIB are linked by inter-molecular N-H⋯N and N-H⋯O hydrogen bonds into layers parallel to (001). These layers are connected along the c-axis direction by weak C-H⋯N contacts. C-H⋯π and C-N⋯π inter-actions connect adjacent mol-ecules, forming chains along the a-axis direction. In (I) and (II), the stability of the packing is ensured by van der Waals inter-actions between the layers. In (I), Hirshfeld surface analysis showed that the most important contributions to the crystal packing are from H⋯H (37.9%), C⋯H/H⋯C (18.4%), Br⋯H/H⋯Br (13.3%), N⋯H/H⋯N (11.5%) and O⋯H/H⋯O (10.0%) inter-actions, while in (II), H⋯H inter-actions are the most significant contributors to the crystal packing (27.6% for mol-ecule IIA and 23.1% for mol-ecule IIB).

Abstract
In the title compound, C19H13BrN2O, the pyridine ring is essentially planar [maximum deviation = 0.024 (4) Å for the N atom] and makes dihedral angles of 74.6 (2) and 65.8 (2)°, respectively, with the phenyl and bromo-phenyl rings, which subtend a dihedral angle of 63.1 (2)°. In the crystal, mol-ecules are connected along the c-axis direction via C-Br⋯π inter-actions, generating zigzag chains parallel to the (010) plane. C-H⋯N and C-H⋯O hydrogen-bonding inter-actions further connect the mol-ecules, forming a three-dimensional network and reinforcing the mol-ecular packing. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯H (36.2%), C⋯H/H⋯C (21.6%), N⋯H/H⋯N (12.2%), and Br⋯H/H⋯Br (10.8%) inter-actions.

Abstract
The title compound, C20H24BrNO2, is chiral at the carbon atoms on either side of the oxygen atom of the oxazolidine ring and crystallizes as a racemate. The 1,3-oxazolidine ring adopts an envelope conformation with the N atom in an endo position. The mean plane of the oxazolidine ring makes dihedral angles of 77.74 (10) and 45.50 (11)°, respectively, with the 4-bromo-phenol and 1,3,5-tri-methyl-benzene rings. In the crystal, adjacent mol-ecules are connected via C-H⋯O hydrogen bonds and C-H⋯π inter-actions into layers parallel to the (200) plane. The packing is strengthened by van der Waals inter-actions between parallel mol-ecular layers. A Hirshfeld surface analysis shows that H⋯H (58.2%), C⋯H/H⋯C (18.9%), and Br⋯H/H⋯Br (11.5%) inter-actions are the most abundant in the crystal packing.

Abstract
The whole mol-ecule of the title compound, C22H19NO2, is generated by twofold rotational symmetry. The N atom exhibits a trigonal-planar geometry and is located on the twofold rotation axis. In the crystal, mol-ecules are linked by C-H⋯O contacts with R 2 2(12) ring motifs, and C-H⋯π inter-actions, resulting in ribbons along the c-axis direction. van der Waals inter-actions between these ribbons consolidate the mol-ecular packing. Hirshfeld surface analysis indicates that the greatest contributions to the crystal packing are from H⋯H (45.5%), C⋯H/H⋯C (38.2%) and O⋯H/H⋯O (16.0%) inter-actions.
