Na Na In As
Na2InAs crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted single-bond geometry to one Na(2), one In(1), and two equivalent As(1) atoms. The Na(1)-Na(2) bond length is 1.40 Å. The Na(1)-In(1) bond length is 1.40 Å. There is one shorter (2.68 Å) and one longer (2.88 Å) Na(1)-As(1) bond length. In the second Na site, Na(2) is bonded in a 2-coordinate geometry to one Na(1) and three equivalent As(1) atoms. There are a spread of Na(2)-As(1) bond distances ranging from 2.89-3.34 Å. In(1) is bonded in a single-bond geometry to one Na(1) and two equivalent As(1) atoms. There is one shorter (2.89 Å) and one longer (3.04 Å) In(1)-As(1) bond length. As(1) is bonded in a 7-coordinate geometry to two equivalent Na(1), three equivalent Na(2), and two equivalent In(1) atoms.
