The structure described by K2CuTeO7 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Cu(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Te(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted L-shaped geometry to one K(1), one Cu(1), and one Te(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent K(1), one Cu(1), and one Te(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent K(1) and one Te(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to four equivalent K(1) atoms. is represented by the CIF file [CIF]
