Materials Data on K(InGa)2 by Materials Project

Abstract

K(InGa)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. K is bonded in a 8-coordinate geometry to eight equivalent In and eight equivalent Ga atoms. All K–In bond lengths are 3.80 Å. All K–Ga bond lengths are 3.63 Å. In is bonded to four equivalent K, four equivalent In, and four equivalent Ga atoms to form a mixture of distorted face, edge, and corner-sharing InK4In4Ga4 cuboctahedra. All In–In bond lengths are 3.39 Å. All In–Ga bond lengths are 2.91 Å. Ga is bonded in a 9-coordinate geometry to four equivalent K, four equivalent In, and one Ga atom. The Ga–Ga bond length is 2.58 Å.
