Materials Data on Na2AgSb by Materials Project
Na2AgSb crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Na1+ is bonded to four equivalent Sb3- atoms to form a mixture of distorted corner, edge, and face-sharing NaSb4 tetrahedra. There are a spread of Na–Sb bond distances ranging from 3.21–3.39 Å. Ag1+ is bonded in a 2-coordinate geometry to two equivalent Ag1+ and two equivalent Sb3- atoms. Both Ag–Ag bond lengths are 2.92 Å. Both Ag–Sb bond lengths are 2.73 Å. Sb3- is bonded in a distorted q6 geometry to eight equivalent Na1+ and two equivalent Ag1+ atoms.
