Ba6YI15 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are six inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to six I1- atoms to form a mixture of distorted edge and corner-sharing BaI6 octahedra. The corner-sharing octahedra tilt angles range from 10–35°.
