Materials Data on Ni3(BO3)2 by Materials Project
Ni3(BO3)2 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are two inequivalent Ni2+ sites. In the first Ni2+ site, Ni2+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing NiO6 octahedra. The corner-sharing octahedra tilt angles range from 56–66°. There are a spread of Ni–O bond distances ranging from 2.05–2.14 Å. In the second Ni2+ site, Ni2+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles are 66°. There are two shorter (2.09 Å) and four longer (2.10 Å) Ni–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 Ni2+ and one B3+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to three Ni2+ and one B3+ atom.
