Materials Data on Na3InAs2 by Materials Project
Abstract
Na3InAs2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are six inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to four As3- atoms to form NaAs4 tetrahedra that share corners with four NaAs4 tetrahedra, corners with four InAs4 tetrahedra, corners with five NaAs5 trigonal bipyramids, edges with two InAs4 tetrahedra, and edges with three NaAs5 trigonal bipyramids. There are a spread of Na–As bond distances ranging from 2.91–2.99 Å. In the second Na1+ site, Na1+ is bonded in a 4-coordinate geometry to four As3- atoms. There are a spread of Na–As bond distances ranging from 3.05–3.30 Å. In the third Na1+ site, Na1+ is bonded in a 5-coordinate geometry to five As3- atoms. There are a spread of Na–As bond distances ranging from 3.17–3.51 Å. In the fourth Na1+ site, Na1+ is bonded to four As3- atoms to form NaAs4 tetrahedra that share corners with two equivalent NaAs4 tetrahedra, corners with six InAs4 tetrahedra, corners with three NaAs5 trigonal bipyramids, an edgeedge with one NaAs4 tetrahedra, an edgeedge with one InAs4 tetrahedra, and edges with three NaAs5 trigonal bipyramids. There are a spread of Na–As bond distances ranging from 2.90–2.98 Å. In themore »
