NaInSn2 crystallizes in the orthorhombic P2_12_12_1 space group. Na(1) is bonded in a 10-coordinate geometry to three equivalent In(1), three equivalent Sn(1), and four equivalent Sn(2) atoms. In(1) is bonded in a 7-coordinate geometry to three equivalent Na(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 7-coordinate geometry to three equivalent Na(1), two equivalent In(1), and two equivalent Sn(2) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to four equivalent Na(1), two equivalent In(1), and two equivalent Sn(1) atoms.
