The material described by KNi2In9 crystallizes in the hexagonal P6/mmm space group. K(1) is bonded to twelve equivalent In(1) atoms to form face-sharing KIn12 cuboctahedra. Ni(1) is bonded in a 9-coordinate geometry to three equivalent In(2) and six equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 12-coordinate geometry to two equivalent K(1), two equivalent Ni(1), four equivalent In(1), and four equivalent In(2) atoms. In the second In site, In(2) is bonded in a linear geometry to two equivalent Ni(1) and eight equivalent In(1) atoms. is represented by the CIF card [CIF]
