K2Ge(O3I)6 crystallizes in the trigonal R-3 space group. K(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. Ge(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one Ge(1), and one I(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one K(1) and one I(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one K(1) and two equivalent I(1) atoms. I(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), and two equivalent O(3) atoms.
