description: NaBaP3(HO2)6 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Na1+ is bonded to seven O2- atoms to form distorted NaO7 pentagonal bipyramids that share corners with five PO4 tetrahedra, an edgeedge with one NaO7 pentagonal bipyramid, and an edgeedge with one PO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.36–2.73 Å. Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.73–2.99 Å. There are three 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 NaO7 pentagonal bipyramid and corners with two PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.64 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent NaO7 pentagonal bipyramids and corners with two PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.64 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one NaO7 pentagonal bipyramid, corners with two PO4 tetrahedra, and an edgeedge with one NaO7 pentagonal bipyramid. There are a spread of P–O bond distances ranging from 1.49–1.64 Å. There are six 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 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 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 0.99 Å. In the sixth 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 P5+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Na1+, one Ba2+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Na1+ and two P5+ atoms. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, one Ba2+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one Na1+, one Ba2+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one Na1+, one Ba2+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted water-like geometry to one Na1+ and two H1+ atoms. In the eleventh O2- site, O2- is bonded in a water-like geometry to two equivalent Ba2+ and two H1+ atoms. In the twelfth O2- site, O2- is bonded in a water-like geometry to one Ba2+ and two H1+ atoms.
