Materials Data on CuBi(PO4)2 by Materials Project
CuBi(PO4)2 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Cu1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.87–1.97 Å. Bi5+ is bonded to six O2- atoms to form distorted BiO6 octahedra that share corners with four PO4 tetrahedra and an edgeedge with one PO4 tetrahedra. There are a spread of Bi–O bond distances ranging from 2.24–2.45 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent BiO6 octahedra. The corner-sharing octahedra tilt angles range from 40–59°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one BiO6 octahedra and an edgeedge with one BiO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Bi5+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu1+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Bi5+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Cu1+, one Bi5+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Bi5+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu1+ and one P5+ atom.
