The compound described by YSb(PbO3)2 crystallizes in the monoclinic C2/c space group. Y(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form YO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 16-24°. Pb(1) is bonded in a 4-coordinate geometry to one O(2), one O(3), and two equivalent O(1) atoms. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with six equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 16-24°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Y(1), two equivalent Pb(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Y(1), one Pb(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Y(1), one Pb(1), and one Sb(1) atom. is represented by the CIF card [CIF]
