KInI4 crystallizes in the orthorhombic Iba2 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to two equivalent I(2) and two equivalent I(4) atoms. In the second K site, K(2) is bonded in a distorted T-shaped geometry to one I(1), one I(3), and one I(5) atom. There are two inequivalent In sites. In the first In site, In(1) is bonded in a tetrahedral geometry to one I(1), one I(4), one I(5), and one I(6) atom. In the second In site, In(2) is bonded in a tetrahedral geometry to two equivalent I(2) and two equivalent I(3) atoms. There are six inequivalent I sites. In the first I site, I(1) is bonded in a water-like geometry to one K(2) and one In(1) atom. In the second I site, I(2) is bonded in a distorted single-bond geometry to one K(1) and one In(2) atom. In the third I site, I(3) is bonded in a water-like geometry to one K(2) and one In(2) atom. In the fourth I site, I(4) is bonded in a single-bond geometry to one K(1) and one In(1) atom. In the fifth I site, I(5) is bonded in a water-like geometry to one K(2) and one In(1) atom. In the sixth I site, I(6) is bonded in a single-bond geometry to one In(1) atom.
