The signals for C3 and C6 cannot be observed due to their position next to the boron atom. Owing to the poor signal-to-noise ratio, the "C-NMR signals of b can no longer be observed. Correct C-H-N-Sn analysis. [31 In the BN/NB isomer, the same sides of the rings are coordinated to tin: in the BN/BN isomer, different sides.

Structure solution using Patterson and difference Fourier methods, refinement according to the block cascade method with SHELXTL. The hydrogen atoms of the CH, groups were refined as "riding groups" and the ring hydrogen atoms were obtained from a difference Fourier synthesis and refined to R =0.066.
