Materials Data on Na3In2Ag by Materials Project

Na3AgIn2 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Na is bonded in a 6-coordinate geometry to two equivalent Ag and four equivalent In atoms. Both Na–Ag bond lengths are 3.41 Å. There are two shorter (3.31 Å) and two longer (3.38 Å) Na–In bond lengths. Ag is bonded to six equivalent Na and six equivalent In atoms to form face-sharing AgNa6In6 cuboctahedra. All Ag–In bond lengths are 2.99 Å. In is bonded in a 9-coordinate geometry to six equivalent Na and three equivalent Ag atoms.

Materials Data on NaIn2Ag by Materials Project

NaAgIn2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two NaAgIn2 ribbons oriented in the (1, 0, 0) direction. Na is bonded in a linear geometry to two equivalent In atoms. Both Na–In bond lengths are 3.11 Å. Ag is bonded in a linear geometry to two equivalent In atoms. Both Ag–In bond lengths are 2.70 Å. In is bonded in a linear geometry to one Na and one Ag atom.
