description: CaCoBP2H5O11 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Ca2+ is bonded to six O2- atoms to form CaO6 octahedra that share corners with five PO4 tetrahedra, an edgeedge with one CaO6 octahedra, and an edgeedge with one CoO6 octahedra. There are a spread of Ca–O bond distances ranging from 2.35–2.45 Å. Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share a cornercorner with one BO4 tetrahedra, corners with four PO4 tetrahedra, an edgeedge with one CaO6 octahedra, and an edgeedge with one CoO6 octahedra. There are a spread of Co–O bond distances ranging from 2.04–2.19 Å. B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share a cornercorner with one CoO6 octahedra and corners with three PO4 tetrahedra. The corner-sharing octahedral tilt angles are 69°. There are a spread of B–O bond distances ranging from 1.47–1.50 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 a cornercorner with one CoO6 octahedra, corners with three equivalent CaO6 octahedra, and corners with two equivalent BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 43–60°. There are a spread of P–O bond distances ranging from 1.52–1.59 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent CaO6 octahedra, corners with three equivalent CoO6 octahedra, and a cornercorner with one BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 48–62°. There are a spread of P–O bond distances ranging from 1.54–1.61 Å. There are five 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 single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 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 eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ca2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Ca2+, one Co2+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one B3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one B3+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one Ca2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Ca2+, one Co2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Co2+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one B3+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one Co2+, one B3+, and one H1+ atom. In the tenth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Co2+ and two H1+ atoms. In the eleventh O2- site, O2- is bonded in a distorted water-like geometry to one Ca2+ and two H1+ atoms.
