YSn(WO4)2 crystallizes in the monoclinic P2/c space group. Y(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. W(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form distorted WO6 octahedra that share corners with four equivalent Sn(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-69°. Sn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SnO6 octahedra that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-69°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Y(1), one W(1), and one Sn(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Y(1), two equivalent W(1), and one Sn(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Y(1), one W(1), and one Sn(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Y(1) and two equivalent W(1) atoms.
