(A) Synthesis of organobismuth dihydride 1. Isolated yield; in brackets, 1H NMR yield using 1,2,4,5-tetramethylbenzene as internal standard. (B) Molecular structure of 1 (front view) with thermal ellipsoids at 50% probability and all hydrogen atoms except Bi bounded hydrogen are omitted for clarity. (C) Molecular structure of 1 (top view) with thermal ellipsoids at 50% probability, and all hydrogen atoms except Bi bounded hydrogen are omitted for clarity. (D) Snippet of the NMR data: (i) 1H NMR spectrum of 1, (ii) 1H NMR spectrum of 1-d 2, (iii) 2H NMR spectrum of 1-d 2. (E) IR spectra of 1 (blue line) and 1-d 2 (red line).
