K3InC12O12F18 crystallizes in the trigonal P-3 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted hexagonal planar geometry to six equivalent O(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to three equivalent O(2) and three equivalent F(3) atoms. In(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal non-coplanar geometry to one F(1), one F(2), and one F(3) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one In(1), and one C(2) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one K(2) and one C(2) atom. There are three inequivalent F sites. In the first F site, F(2) is bonded in a single-bond geometry to one C(1) atom. In the second F site, F(3) is bonded in a single-bond geometry to one K(2) and one C(1) atom. In the third F site, F(1) is bonded in a single-bond geometry to one C(1) atom.
