KIn(GeO3)4 crystallizes in the orthorhombic Amm2 space group. K(1) is bonded in a 10-coordinate geometry to two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms. In(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. Ge(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form corner-sharing GeO6 octahedra. The corner-sharing octahedral tilt angles range from 13-34°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one In(1) and two equivalent Ge(1) atoms. In the third O site, O(3) is bonded in a distorted square co-planar geometry to one K(1), one In(1), and two equivalent Ge(1) atoms. In the fourth O site, O(4) is bonded in a distorted square co-planar geometry to two equivalent K(1) and two equivalent Ge(1) atoms. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one In(1) and two equivalent Ge(1) atoms.
