RESUMEN
In the title compound, C18H22O7, two hexane rings and an oxane ring are fused together. The two hexane rings tend toward a distorted boat conformation, while the tetra-hydro-furan and di-hydro-furan rings adopt envelope conformations. The oxane ring is puckered. The crystal structure features C-Hâ¯O hydrogen bonds, which link the mol-ecules into a three-dimensional network. According to a Hirshfeld surface study, Hâ¯H (60.3%) and Oâ¯H/Hâ¯O (35.3%) inter-actions are the most significant contributors to the crystal packing.
RESUMEN
In the title compound, C20H18N2S, the asymmetric unit comprises two similar mol-ecules (A and B). In mol-ecule A, the central thio-phene ring makes dihedral angles of 89.96â (12) and 57.39â (13)° with the 1H-pyrrole rings, which are bent at 83.22â (14)° relative to each other, and makes an angle of 85.98â (11)° with the phenyl ring. In mol-ecule B, the corresponding dihedral angles are 89.49â (13), 54.64â (12)°, 83.62â (14)° and 85.67â (11)°, respectively. In the crystal, mol-ecular pairs are bonded to each other by N-Hâ¯N inter-actions. N-Hâ¯π and C-Hâ¯π inter-actions further connect the mol-ecules, forming a three-dimensional network. A Hirshfeld surface analysis indicates that Hâ¯H (57.1% for mol-ecule A; 57.3% for mol-ecule B), Câ¯H/Hâ¯C (30.7% for mol-ecules A and B) and Sâ¯H/Hâ¯S (6.2% for mol-ecule A; 6.4% for mol-ecule B) inter-actions are the most important contributors to the crystal packing.
RESUMEN
In the title compound, C25H25NO7S, the mol-ecular conformation is stabilized by intra-molecular O-Hâ¯O and N-Hâ¯O hydrogen bonds, which form S(6) and S(8) ring motifs, respectively. The mol-ecules are bent at the S atom with a C-SO2-NH-C torsion angle of -70.86â (11)°. In the crystal, mol-ecules are linked by C-Hâ¯O and N-Hâ¯O hydrogen bonds, forming mol-ecular layers parallel to the (100) plane. C-Hâ¯π inter-actions are observed between these layers.
RESUMEN
The title mol-ecule, C18H16F3NO7, comprises a fused cyclic system containing four five-membered (two di-hydro-furan and two tetra-hydro-furan) rings and one six-membered (piperidine) ring. The five-membered di-hydro-furan and tetra-hydro-furan rings adopt envelope conformations, and the six-membered piperidine ring adopts a distorted chair conformation. Intra-molecular Oâ¯F inter-actions help to stabilize the conformational arrangement. In the crystal structure, mol-ecules are linked by weak C-Hâ¯O and C-Hâ¯F hydrogen bonds, forming a three-dimensional network. The Hirshfeld surface analysis confirms the dominant role of Hâ¯H contacts in establishing the packing.
