Materials Data on KNa4GaO4 by Materials Project
Abstract
KNa4GaO4 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. K1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of K–O bond distances ranging from 2.66–2.84 Å. There are four inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are a spread of Na–O bond distances ranging from 2.36–2.45 Å. In the second Na1+ site, Na1+ is bonded to four O2- atoms to form distorted NaO4 tetrahedra that share corners with two equivalent GaO4 tetrahedra, corners with five NaO4 tetrahedra, and an edgeedge with one GaO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.31–2.47 Å. In the third Na1+ site, Na1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Na–O bond distances ranging from 2.37–2.63 Å. In the fourth Na1+ site, Na1+ is bonded to four O2- atoms to form distorted NaO4 tetrahedra that share corners with two equivalent GaO4 tetrahedra, corners with three equivalent NaO4 tetrahedra, an edgeedge with one NaO4 tetrahedra, and an edgeedge with one GaO4 tetrahedra. There are a spread of Na–O bond distances rangingmore »

In the first O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent K1+, three Na1+, and one Ga3+ atom. In the second O2- site, O2- is bonded to five Na1+ and one Ga3+ atom to form corner-sharing ONa5Ga octahedra. The corner-sharing octahedra tilt angles range from 48–70°. In the third O2- site, O2- is bonded in a 6-coordinate geometry to one K1+, four Na1+, and one Ga3+ atom. In the fourth O2- site, O2- is bonded in a 6-coordinate geometry to one K1+, four Na1+, and one Ga3+ atom.},
