Abstract

Na2LiGaAs2 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first 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 3.04–3.21 Å. In the second Na1+ site, Na1+ is bonded to five As3- atoms to form distorted NaAs5 trigonal bipyramids that share corners with six equivalent LiAs4 tetrahedra, corners with six equivalent GaAs4 tetrahedra, corners with four equivalent NaAs5 trigonal bipyramids, edges with two equivalent LiAs4 tetrahedra, edges with two equivalent GaAs4 tetrahedra, and edges with two equivalent NaAs5 trigonal bipyramids. There are a spread of Na–As bond distances ranging from 3.08–3.20 Å. Li1+ is bonded to four As3- atoms to form LiAs4 tetrahedra that share corners with two equivalent LiAs4 tetrahedra, corners with two equivalent GaAs4 tetrahedra, corners with six equivalent NaAs5 trigonal bipyramids, an edgeedge with one LiAs4 tetrahedra, edges with three equivalent GaAs4 tetrahedra, and edges with two equivalent NaAs5 trigonal bipyramids.
