Zn2PbAs2O10 crystallizes in the monoclinic C2/m space group. Zn(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form ZnO6 octahedra that share corners with two equivalent Pb(1)O6 octahedra, corners with four equivalent As(1)O4 tetrahedra, and edges with two equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 63°. Pb(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form PbO6 octahedra that share corners with four equivalent Zn(1)O6 octahedra and corners with six equivalent As(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 63°. As(1) is bonded to one O(2), one O(4), and two equivalent O(3) atoms to form AsO4 tetrahedra that share corners with three equivalent Pb(1)O6 octahedra and corners with four equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 53-67°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Zn(1) and one O(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Pb(1) and one As(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Zn(1), one Pb(1), and one As(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to two equivalent Zn(1) and one As(1) atom.
