Na2SbAs crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 6-coordinate geometry to three equivalent Sb(1) and three equivalent As(1) atoms. In the second Na site, Na(2) is bonded in a 6-coordinate geometry to three equivalent Sb(1) and three equivalent As(1) atoms. Sb(1) is bonded in a 8-coordinate geometry to three equivalent Na(1), three equivalent Na(2), and two equivalent As(1) atoms. As(1) is bonded to three equivalent Na(1), three equivalent Na(2), and two equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing AsNa6Sb2 hexagonal bipyramids.
Na2SbAs crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 6-coordinate geometry to three equivalent Sb(1) and three equivalent As(1) atoms. There are a spread of Na(1)-Sb(1) bond distances ranging from 3.19-3.23 Å. There are a spread of Na(1)-As(1) bond distances ranging from 3.23-3.31 Å. In the second Na site, Na(2) is bonded in a 6-coordinate geometry to three equivalent Sb(1) and three equivalent As(1) atoms. There is one shorter (3.25 Å) and two longer (3.26 Å) Na(2)-Sb(1) bond lengths. There are a spread of Na(2)-As(1) bond distances ranging from 3.17-3.31 Å. Sb(1) is bonded in a 8-coordinate geometry to three equivalent Na(1), three equivalent Na(2), and two equivalent As(1) atoms. There is one shorter (2.68 Å) and one longer (2.71 Å) Sb(1)-As(1) bond length. As(1) is bonded to three equivalent Na(1), three equivalent Na(2), and two equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing AsNa6Sb2 hexagonal bipyramids.
