Materials Data on NaGdP2H2CO7 by Materials Project
Abstract
NaGdCP2H2O7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with five PCO3 tetrahedra and an edgeedge with one NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.34–2.82 Å. Gd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Gd–O bond distances ranging from 2.26–2.60 Å. C2- is bonded in a distorted tetrahedral geometry to two P5+ and two H1+ atoms. There is one shorter (1.81 Å) and one longer (1.83 Å) C–P bond length. Both C–H bond lengths are 1.10 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to one C2- and three O2- atoms to form PCO3 tetrahedra that share corners with three equivalent NaO6 octahedra and a cornercorner with one PCO3 tetrahedra. The corner-sharing octahedra tilt angles range from 58–63°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. In the second P5+ site, P5+ is bonded to one C2- and three O2- atoms to form PCO3 tetrahedra that share corners with two equivalent NaO6 octahedra and a cornercorner withmore »
