Crystal structure, Hirshfeld surface analysis and inter-action energy calculation of 1-decyl-2,3-di-hydro-1H-benzimidazol-2-one.

ABSTRACT: The title mol-ecule, C₁₇H₂₆N₂O, adopts an L-shaped conformation, with the straight n-decyl chain positioned nearly perpendicular to the di-hydro-benzimidazole moiety. The di-hydro-benzimidazole portion is not quite planar as there is a dihedral angle of 1.20 (6)° between the constituent planes. In the crystal, N-H⋯O hydrogen bonds form inversion dimers, which are connected into the three-dimensional structure by C-H⋯O hydrogen bonds and C-H⋯π(ring) inter-actions. Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are from H⋯H (75.9%), H⋯C/C⋯H (12.5%) and H⋯O/O⋯H (7.0%) inter-actions. Based on computational chemistry using the CE-B3LYP/6-31 G(d,p) energy model, C-H⋯O hydrogen bond energies are -74.9 (for N-H⋯O) and -42.7 (for C-H⋯O) kJ mol^-1.

Project description:The title compound, C18H16N2O2, consists of perimidine and meth-oxy-phenol units, where the tricyclic perimidine unit contains a naphthalene ring system and a non-planar C4N2 ring adopting an envelope conformation with the NCN group hinged by 47.44?(7)° with respect to the best plane of the other five atoms. In the crystal, O-HPhnl?NPrmdn and N-HPrmdn?OPhnl (Phnl = phenol and Prmdn = perimidine) hydrogen bonds link the mol-ecules into infinite chains along the b-axis direction. Weak C-H?? inter-actions may further stabilize the crystal structure.

Project description:In the title mol-ecule, C11H10N2O, the di-hydro-benzimidazol-2-one moiety is essentially planar, with the prop-2-yn-1-yl substituent rotated well out of this plane. In the crystal, C-HMthy⋯π(ring) inter-actions and C-HProp⋯ODhyr (Mthy = methyl, Prop = prop-2-yn-1-yl and Dhyr = di-hydro) hydrogen bonds form corrugated layers parallel to (10), which are associated through additional C-HBnz⋯ODhyr (Bnz = benzene) hydrogen bonds and head-to-tail, slipped, π-stacking [centroid-to-centroid distance = 3.7712 (7) Å] inter-actions between di-hydro-benzimidazol-2-one moieties. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H⋯H (44.1%), H⋯C/C⋯H (33.5%) and O⋯H/H⋯O (13.4%) inter-actions. Hydrogen-bonding and van der Waals inter-actions are the dominant inter-actions in the crystal packing.

Project description:The title compound {systematic name: (S,E)-3-[4-(furan-2-yl)-2,3,4,5-tetra-hydro-1H-benzo[b][1,4]diazepin-2-yl-idene]-6-methyl-2H-pyran-2,4(3H)-dione}, C19H16N2O4, is constructed from a benzodiazepine ring system linked to furan and pendant di-hydro-pyran rings, where the benzene and furan rings are oriented at a dihedral angle of 48.7 (2)°. The pyran ring is modestly non-planar [largest deviation of 0.029 (4) Å from the least-squares plane] while the tetra-hydro-diazepine ring adopts a boat conformation. The rotational orientation of the pendant di-hydro-pyran ring is partially determined by an intra-molecular N-HDiazp⋯ODhydp (Diazp = diazepine and Dhydp = di-hydro-pyran) hydrogen bond. In the crystal, layers of mol-ecules parallel to the bc plane are formed by N-HDiazp⋯ODhydp hydrogen bonds and slipped π-π stacking inter-actions. The layers are connected by additional slipped π-π stacking inter-actions. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (46.8%), H⋯O/O⋯H (23.5%) and H⋯C/C⋯H (15.8%) inter-actions, indicating that van der Waals inter-actions are the dominant forces in the crystal packing.

Project description:In the title compound, C12H12N2O4, the di-hydro-pyrrole ring is almost planar (r.m.s. deviation = 0.0049?Å) and is nearly coplanar with the adjacent C2O2 residue [dihedral angle = 4.56?(9)°], which links to the 4-nitro-benzene substituent [dihedral angle = 4.58?(8)°]. The mol-ecule is concave, with the outer rings lying to the same side of the central C2O2 residue and being inclined to each other [dihedral angle = 8.30?(7)°]. In the crystal, supra-molecular layers parallel to (10-5) are sustained by nitro-benzene-C-H?O(carbon-yl) and pyrrole-C-H?O(nitro) inter-actions. The layers are connected into a three-dimensional architecture by ?(pyrrole)-?(nitro-benzene) stacking [inter-centroid separation = 3.7414?(10)?Å] and nitro-O??(pyrrole) inter-actions.

Crystal structure, Hirshfeld surface analysis and inter-action energy and DFT studies of 3-{(2Z)-2-[(2,4-di-chloro-phen-yl)methyl-idene]-3-oxo-3,4-di-hydro-2H-1,4-benzo-thia-zin-4-yl}propane-nitrile.

Project description:The title compound, C18H12Cl2N2OS, consists of a di-hydro-benzo-thia-zine unit linked by a -CH group to a 2,4-di-chloro-phenyl substituent, and to a propane-nitrile unit is folded along the S⋯N axis and adopts a flattened-boat conformation. The propane-nitrile moiety is nearly perpendicular to the mean plane of the di-hydro-benzo-thia-zine unit. In the crystal, C-HBnz⋯NPrpnit and C-HPrpnit⋯OThz (Bnz = benzene, Prpnit = propane-nitrile and Thz = thia-zine) hydrogen bonds link the mol-ecules into inversion dimers, enclosing R 2 2(16) and R 2 2(12) ring motifs, which are linked into stepped ribbons extending along [110]. The ribbons are linked in pairs by complementary C=O⋯Cl inter-actions. π-π contacts between the benzene and phenyl rings, [centroid-centroid distance = 3.974 (1) Å] may further stabilize the structure. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (23.4%), H⋯Cl/Cl⋯H (19.5%), H⋯C/C⋯H (13.5%), H⋯N/N⋯H (13.3%), C⋯C (10.4%) and H⋯O/O⋯H (5.1%) inter-actions. Hydrogen bonding and van der Waals inter-actions are the dominant inter-actions in the crystal packing. Computational chemistry calculations indicate that the two independent C-HBnz⋯NPrpnit and C-HPrpnit⋯OThz hydrogen bonds in the crystal impart about the same energy (ca 43 kJ mol-1). Density functional theory (DFT) optimized structures at the B3LYP/6-311 G(d,p) level are compared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap.

Density functional theory (DFT) optimized structures at the B3LYP/ 6-311?G(d,p) level are compared with the experimentally determined mol-ecular structure in the solid state.
