Crystal structure and Hirshfeld surface analysis of 5,5-difluoro-10-[5-(trimethylsilyl)furan-2-yl]-5H-4λ4,5λ4-dipyrrolo[1,2-c:2′,1′-f][1,3,2]diazaborinine

In the title compound, C16H17BF2N2OSi, the molecular conformation is consolidated by an intramolecular C-H⋯O hydrogen bond, forming an S(6) motif. In the crystal, pairs of molecules are connected by C-H⋯π and π-π interactions [centroid-to-centroid distance = 3.6155 (8) Å] between the furan rings. These dimers are linked by π-π interactions [centroid-to-centroid distance = 3.4041 (9) Å] between similar five-membered rings of the twelve-membered ring system, forming ribbons along the a-axis direction. As a result, the van der Waals interactions between the ribbons provide crystal cohesion. Hirshfeld surface analysis indicates that H⋯H (48.6%), F⋯H/H⋯F (19.8%) and C⋯H/ H⋯C (19.0%) interactions make the most significant contributions to the crystal packing. © 2025 Elsevier B.V., All rights reserved.
