description: CoBP(HO3)2 crystallizes in the trigonal P3_1 space group. The structure is three-dimensional. there are two inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded to six O2- atoms to form distorted CoO6 octahedra that share a cornercorner with one BO4 tetrahedra, corners with four PO4 tetrahedra, and edges with two equivalent CoO5 trigonal bipyramids. There are a spread of Co–O bond distances ranging from 1.94–2.36 Å. In the second Co2+ site, Co2+ is bonded to five O2- atoms to form distorted CoO5 trigonal bipyramids that share a cornercorner with one BO4 tetrahedra, corners with four PO4 tetrahedra, and edges with two equivalent CoO6 octahedra. There are a spread of Co–O bond distances ranging from 1.98–2.38 Å. There are two inequivalent B3+ sites. In the first 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 1.32–1.43 Å. In the second B3+ site, B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share a cornercorner with one CoO6 octahedra, corners with two PO4 tetrahedra, and a cornercorner with one CoO5 trigonal bipyramid. The corner-sharing octahedral tilt angles are 49°. There are a spread of B–O bond distances ranging from 1.46–1.52 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent CoO6 octahedra, a cornercorner with one BO4 tetrahedra, and corners with two equivalent CoO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 57–61°. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent CoO6 octahedra, a cornercorner with one BO4 tetrahedra, and corners with two equivalent CoO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 46–60°. There are a spread of P–O bond distances ranging from 1.53–1.58 Å. There are four inequivalent H1+ sites. In the first 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 second H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Co2+, one B3+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to one B3+ and one H1+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Co2+ and one B3+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Co2+, one B3+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two Co2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two Co2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one B3+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one B3+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one B3+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the eleventh O2- site, O2- is bonded in a 3-coordinate geometry to two Co2+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Co2+ and one P5+ atom.
