Abstract The discovery of fullerene following the synthesis of graphene marked a paradigm shift in chemistry.Here, tyrolia attack2 14 gw we report the discovery of biycycloborane, arising from the synthesis of borophane (hydrogen boride).Uniquely, this synthesis method involves a decomposition mechanism rather than traditional atom-by-atom assembly, marking an unique approach to constructing complex borane structures.The mass spectrometry unveiled that the stable molecule has a mass of 178 in atomic mass unit with a stoichiometry of B14H26.Optical spectra and simulations further evidenced its bicyclic structure, featuring fulvene-like heptagons or octagons.

This borane molecule, analogous to cyclic igora vibrance 6-16 hydrocarbons, adopts a unit configuration with a three-center two-electron (3c-2e) bonding, akin to diborane.The B14H26 molecule has been historically anticipated as a distant descendant of the dodecahedron borane, but it was born from the hydrogen boride sheet with a non-symmorphic symmetry.The discovery of biycycloborane expands the frontiers of boron chemistry, promising advancements in boron-based nanomaterials and beyond.
