K3In is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to four equivalent K(2) and four equivalent In(1) atoms to form a mixture of distorted edge, face, and corner-sharing KK4In4 tetrahedra. In the second K site, K(2) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms. In(1) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms.
