Intermolecular arenecentroid⋯H–C tBu interactions, shown as dashed lines, that guide the packing arrangement for 1. The H23B⋯C5→C10centroid and H32B⋯C5→C10centroid contacts are 3.00 and 2.90 Å, respectively. Symmetry transformation used to generate equivalent molecules: − x, − + y, − z; − − x, + y, − z. |
