. The structure was solved by direct methods and was refined by full-matrix least-squares procedures to R = 0.045 and R
w
= 0.042 for 2914 reflections with I ≥ 2σ(I). The envelope-like conformation adopted by the seven-membered chelate ring places one B-phenyl group above the plane of the fused-ring system facilitating a thermally-induced 1,4-migration of a B-phenyl group to the nitrone carbon atom. Mean bond lengths (corrected for libration) are (N)OB = 1.559(6), (C)OB = 1.496(3), CB = 1.610(4) Å. |
