In the fifth B3+ site, B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with two equivalent ZnO6 octahedra and corners with two equivalent BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 61–64°. There are a spread of B–O bond distances ranging from 1.43–1.57 Å. In the sixth B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.37–1.40 Å. There are five inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.62 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.56 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms. In the second O2- site, O2- is bonded in a trigonal planar geometry to two B3+ and one H1+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to two B3+ and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two B3+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Zn2+ and two B3+ atoms. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to one Zn2+ and two B3+ atoms. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one B3+ and one H1+ atom.
