Materials Data on Mn3(BO3)2 by Materials Project

Mn3(BO3)2 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing MnO6 octahedra. The corner-sharing octahedra tilt angles range from 58–70°. There are a spread of Mn–O bond distances ranging from 2.18–2.30 Å. In the second Mn2+ site, Mn2+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 70°. There are two shorter (2.19 Å) and four longer (2.25 Å) Mn–O bond lengths. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.38 Å) and two longer (1.40 Å) B–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three Mn2+ and one B3+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Mn2+ and one B3+ atom.
