Zn3(BO3)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are six inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to four O2- atoms to form corner-sharing ZnO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.96–2.04 Å. In the second Zn2+ site, Zn2+ is bonded to four O2- atoms to form corner-sharing ZnO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.97–2.03 Å. In the third Zn2+ site, Zn2+ is bonded to four O2- atoms to form corner-sharing ZnO4 tetrahedra. There is two shorter (1.96 Å) and two longer (1.98 Å) Zn–O bond length. In the fourth Zn2+ site, Zn2+ is bonded to four O2- atoms to form corner-sharing ZnO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.95–2.03 Å. In the fifth Zn2+ site, Zn2+ is bonded to four O2- atoms to form corner-sharing ZnO4 tetrahedra. There is one shorter (1.95 Å) and three longer (1.99 Å) Zn–O bond length. In the sixth Zn2+ site, Zn2+ is bonded to four O2- atoms to form corner-sharing ZnO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.96–2.04 Å. There are four inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.39 Å) and one longer (1.40 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.38 Å) and one longer (1.39 Å) B–O bond length. In the third B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.38 Å) and two longer (1.39 Å) B–O bond length. In the fourth B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.38 Å) and two longer (1.39 Å) B–O bond length. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two Zn2+ and one B3+ atom. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Zn2+ and one B3+ atom.
