The crystal structure described by YCu3Se2O8Cl crystallizes in the orthorhombic Pmmn space group. Y(1) is bonded in a body-centered cubic geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a square co-planar geometry to two equivalent O(1), two equivalent O(3), and two equivalent Cl(1) atoms. In the second Cu site, Cu(2) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. Se(1) is bonded in a trigonal non-coplanar geometry to one O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Y(1), one Cu(2), and two equivalent Cu(1) atoms to form a mixture of edge and corner-sharing OYCu3 tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to one Y(1), one Cu(2), and one Se(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Y(1), one Cu(1), and one Se(1) atom. Cl(1) is bonded in a 4-coordinate geometry to four equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
