KV3(SeO6)2 crystallizes in the hexagonal P6_3 space group. K(1) is bonded in a 6-coordinate geometry to three equivalent O(2) and three equivalent O(3) atoms. V(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 36-39°. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a trigonal non-coplanar geometry to three equivalent O(1) atoms. In the second Se site, Se(2) is bonded in a trigonal non-coplanar geometry to three equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one V(1) and one Se(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one K(1), one V(1), and one Se(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one K(1) and two equivalent V(1) atoms. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to two equivalent V(1) atoms.
