Na Na In Bi
Na2InBi crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 2-coordinate geometry to one Na(2) and two equivalent Bi(1) atoms. The Na(1)-Na(2) bond length is 0.55 Å. There is one shorter (2.89 Å) and one longer (3.46 Å) Na(1)-Bi(1) bond length. In the second Na site, Na(2) is bonded in a 2-coordinate geometry to one Na(1), one In(1), and one Bi(1) atom. The Na(2)-In(1) bond length is 2.89 Å. The Na(2)-Bi(1) bond length is 3.80 Å. In(1) is bonded in a 2-coordinate geometry to one Na(2) and two equivalent Bi(1) atoms. There is one shorter (2.72 Å) and one longer (3.28 Å) In(1)-Bi(1) bond length. Bi(1) is bonded in a 7-coordinate geometry to one Na(2), two equivalent Na(1), two equivalent In(1), and two equivalent Bi(1) atoms. Both Bi(1)-Bi(1) bond lengths are 3.32 Å.
