Pb2ScSbO6 crystallizes in the orthorhombic Imm2 space group. Sc(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form ScO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 1-5°. Pb(1) is bonded in a 3-coordinate geometry to one O(2) 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 Sc(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 1-5°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Sc(1), two equivalent Pb(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to one Sc(1), one Pb(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a linear geometry to one Sc(1) and one Sb(1) atom.
