Cu3B7O13I is cubic, space group F̅43c, with a 12.0203(7) Å; d.(calcd.) = 4.608 for Z = 8. Final R = 0.014 for 110 unique reflections. At. parameters are given. This new boracite has been prepared by high-pressure synthesis; its structure is comparable with that of other cubic boracites. No structural phase transition could be observed between 15 and 1265 K
