The material structure described by KIn4 crystallizes in the tetragonal I4/mmm space group. K(1) is bonded in a 16-coordinate geometry to eight equivalent In(1) and eight equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent K(1), four equivalent In(1), and four equivalent In(2) atoms to form a mixture of distorted corner, face, and edge-sharing InK4In8 cuboctahedra. In the second In site, In(2) is bonded in a 9-coordinate geometry to four equivalent K(1), one In(2), and four equivalent In(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
