RESUMO
In the title compound, C19H18BrFN2O, the pyrrolidine ring adopts an envelope conformation. In the crystal, mol-ecules are linked by inter-molecular N-Hâ¯O, C-Hâ¯O, C-Hâ¯F and C-Hâ¯Br hydrogen bonds, forming a three-dimensional network. In addition, C-Hâ¯π inter-actions connect mol-ecules into ribbons along the b-axis direction, consolidating the mol-ecular packing. The inter-molecular inter-actions in the crystal structure were qu-anti-fied and analysed using Hirshfeld surface analysis.
RESUMO
In the title compound, C15H13NO3S, the mol-ecular conformation is stable with the intra-molecular O-Hâ¯O hydrogen bond forming a S(7) ring motif. In the crystal, mol-ecules are connected by C-Hâ¯O hydrogen bonds, forming C(8) chains running along the a-axis direction. Cohesion of the packing is provided by weak van der Waals inter-actions between the chains. A Hirshfeld surface analysis was undertaken to investigate and qu-antify the inter-molecular inter-actions. The thio-phene ring is disordered in a 0.9466â (17):0.0534â (17) ratio over two positions rotated by 180°.
RESUMO
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.
