KNb4InO12 crystallizes in the orthorhombic Amm2 space group. K(1) is bonded in a distorted q6 geometry to two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms. Nb(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 NbO6 octahedra. The corner-sharing octahedral tilt angles range from 19-47°. In(1) is bonded in a 4-coordinate geometry to two equivalent O(2) and two equivalent O(5) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one K(1) and two equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent Nb(1) and one In(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one K(1) and two equivalent Nb(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent Nb(1) atoms. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to two equivalent Nb(1) and one In(1) atom.
