Abstract

-008Crystal Structure of Boron Triiodide, BI 3 .-The air-and light sensitive title compound is obtained as microcrystalline powder by sublimation (vacuum, 23 → -196 • C) of the reaction product of NaBH 4 and I 2 (hexane, reflux, 84 h). BI 3 crystallizes in the hexagonal space group P6 3 /m with Z = 2. The B-I bond length is determined to be 211.2 pm.
