Crystal structure and Hirshfeld surface analysis of 5,5-di-fluoro-10-[5-(tri-methyl-sil-yl)furan-2-yl]-5H-4λ4,5λ4-di-pyrrolo-[1,2-c:2',1'-f][1,3,2]di-aza-borinine.

In the title compound, C16H17BF2N2OSi, the mol-ecular conformation is consolidated by an intra-molecular C-H⋯O hydrogen bond, forming an S(6) motif. In the crystal, pairs of mol-ecules are connected by C-H⋯π and π-π inter-actions [centroid-to-centroid distance = 3.6155 (8) Å] between the furan rings. These dimers are linked by π-π inter-actions [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 inter-actions 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%) inter-actions make the most significant contributions to the crystal packing.
