Materials Data on Na3BiBPO7 by Materials Project
Na3BBiPO7 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.47–2.85 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.27–2.59 Å. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.34–1.43 Å. Bi3+ is bonded to six O2- atoms to form distorted BiO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Bi–O bond distances ranging from 2.26–2.59 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent BiO6 octahedra. The corner-sharing octahedra tilt angles range from 46–68°. There is one shorter (1.55 Å) and three longer (1.57 Å) P–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to four Na1+ and one B3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Na1+, one B3+, and one Bi3+ atom. In the third O2- site, O2- is bonded to three Na1+, one B3+, and one Bi3+ atom to form distorted corner-sharing ONa3BiB trigonal bipyramids. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two Na1+, one Bi3+, and one P5+ atom. In the fifth O2- site, O2- is bonded to two equivalent Na1+, one Bi3+, and one P5+ atom to form distorted corner-sharing ONa2BiP tetrahedra. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, one Bi3+, and one P5+ atom.
