K2Ge2O3 crystallizes in the cubic I2_13 space group. K(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Ge(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. O(1) is bonded to four equivalent K(1) and two equivalent Ge(1) atoms to form a mixture of distorted edge, corner, and face-sharing OK4Ge2 octahedra. The corner-sharing octahedral tilt angles range from 60-61°.
K2Ge2O3 crystallizes in the cubic I2_13 space group. K(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are three shorter (2.81 Å) and three longer (2.89 Å) K(1)-O(1) bond lengths. Ge(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. All Ge(1)-O(1) bond lengths are 1.88 Å. O(1) is bonded to four equivalent K(1) and two equivalent Ge(1) atoms to form a mixture of distorted edge, corner, and face-sharing OK4Ge2 octahedra. The corner-sharing octahedral tilt angles range from 60-61°.
