Materials Data on Na3CuSiCO7 by Materials Project
Abstract
Na3CuSiCO7 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 2.40–2.68 Å. In the second Na1+ site, Na1+ is bonded to seven O2- atoms to form distorted NaO7 pentagonal bipyramids that share a cornercorner with one CuO6 octahedra, corners with two equivalent NaO7 pentagonal bipyramids, corners with two equivalent SiO4 tetrahedra, an edgeedge with one CuO6 octahedra, an edgeedge with one NaO7 pentagonal bipyramid, an edgeedge with one SiO4 tetrahedra, a faceface with one CuO6 octahedra, and a faceface with one NaO7 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 61°. There are a spread of Na–O bond distances ranging from 2.24–2.78 Å. Cu3+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with two equivalent NaO7 pentagonal bipyramids, corners with four equivalent SiO4 tetrahedra, edges with two equivalent NaO7 pentagonal bipyramids, and faces with two equivalent NaO7 pentagonal bipyramids. There are a spread of Cu–O bond distances ranging from 1.97–2.36 Å. Si4+ is bonded to four O2- atoms to formmore »

The corner-sharing octahedral tilt angles are 61°. There are a spread of Na–O bond distances ranging from 2.24–2.78 Å.

There are a spread of Cu–O bond distances ranging from 1.97–2.36 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with four equivalent CuO6 octahedra, corners with four equivalent NaO7 pentagonal bipyramids, and edges with two equivalent NaO7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 43–52°. There are a spread of Si–O bond distances ranging from 1.63–1.66 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.29 Å) and two longer (1.30 Å) C–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 C4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Na1+, one Cu3+, and one C4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three Na1+, one Cu3+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to three Na1+, one Cu3+, and one Si4+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+, one Cu3+, and one Si4+ atom. In the sixth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na1+, one Cu3+, and one Si4+ atom.},
