Abstract

EuCPH3O6H2O crystallizes in the triclinic P-1 space group. The structure is three-dimensional and consists of two water molecules and one EuCPH3O6 framework. In the EuCPH3O6 framework, Eu2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.38–2.57 Å. C2+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.26 Å. P5+ is bonded in a distorted tetrahedral geometry to one H1+ and three O2- atoms. The P–H bond length is 1.41 Å. There are a spread of P–O bond distances ranging from 1.53–1.55 Å. There are three 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 P5+ atom. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Eu2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Eu2+ and one C2+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Eu2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Eu2+ and one C2+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Eu2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to one Eu2+ and two H1+ atoms.
