Ba3(BO3)2 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing BaO6 octahedra. The corner-sharing octahedral tilt angles are 82°. There are two shorter (2.64 Å) and four longer (2.74 Å) Ba–O bond lengths. In the second Ba2+ site, Ba2+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing BaO6 octahedra. The corner-sharing octahedra tilt angles range from 64–82°. There are a spread of Ba–O bond distances ranging from 2.72–2.78 Å. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.39 Å) and two longer (1.41 Å) B–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+ and one B3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+ and one B3+ atom.
