Abstract

Na3InBi2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are nine inequivalent Na sites. In the first Na site, Na is bonded to one In and four Bi atoms to form a mixture of distorted edge and corner-sharing NaInBi4 tetrahedra. The Na–In bond length is 3.75 Å. There are a spread of Na–Bi bond distances ranging from 3.21–3.37 Å. In the second Na site, Na is bonded to four Bi atoms to form distorted corner-sharing NaBi4 tetrahedra. There are a spread of Na–Bi bond distances ranging from 3.25–3.35 Å. In the third Na site, Na is bonded in a 5-coordinate geometry to one In and five Bi atoms. The Na–In bond length is 3.70 Å. There are a spread of Na–Bi bond distances ranging from 3.39–3.66 Å. In the fourth Na site, Na is bonded to one In and four Bi atoms to form a mixture of distorted edge and corner-sharing NaInBi4 tetrahedra. The Na–In bond length is 3.87 Å.
