The compound described by Au2Se4O11 crystallizes in the monoclinic C2/c space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a square co-planar geometry to two equivalent O(4) and two equivalent O(6) atoms. In the second Au site, Au(2) is bonded in a square co-planar geometry to two equivalent O(3) and two equivalent O(5) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom. In the second Se site, Se(2) is bonded in a distorted T-shaped geometry to one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(4) is bonded in a bent 120 degrees geometry to one Au(1) and one Se(2) atom. In the second O site, O(5) is bonded in a bent 120 degrees geometry to one Au(2) and one Se(2) atom. In the third O site, O(6) is bonded in a bent 120 degrees geometry to one Au(1) and one Se(2) atom. In the fourth O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Se(1) atoms. In the fifth O site, O(2) is bonded in a single-bond geometry to one Se(1) atom. In the sixth O site, O(3) is bonded in a bent 120 degrees geometry to one Au(2) and one Se(1) atom. is represented by the CIF card [CIF]
