Abstract

MnPH5O7H2 crystallizes in the orthorhombic Pbca space group. The structure is zero-dimensional and consists of eight hydrogen molecules and four MnPH5O7 clusters. In each MnPH5O7 cluster, Mn2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Mn–O bond distances ranging from 1.65–2.08 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.51–1.64 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 distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.68 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 0.98 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 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 seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one P5+ and two H1+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Mn2+ and one P5+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Mn2+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a water-like geometry to one Mn2+ and one H1+ atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to one Mn2+ atom.
