Cd2PbO4 crystallizes in the orthorhombic Pbam space group. Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted CdO6 pentagonal pyramids that share corners with four equivalent Pb(1)O6 octahedra, corners with four equivalent Cd(1)O6 pentagonal pyramids, edges with two equivalent Pb(1)O6 octahedra, and edges with five equivalent Cd(1)O6 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 52-73°. Pb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form PbO6 octahedra that share corners with eight equivalent Cd(1)O6 pentagonal pyramids, edges with two equivalent Pb(1)O6 octahedra, and edges with four equivalent Cd(1)O6 pentagonal pyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Cd(1) and one Pb(1) atom to form distorted OCd4Pb trigonal bipyramids that share corners with five equivalent O(1)Cd4Pb trigonal bipyramids, corners with eight equivalent O(2)Cd2Pb2 trigonal pyramids, edges with four equivalent O(1)Cd4Pb trigonal bipyramids, and edges with two equivalent O(2)Cd2Pb2 trigonal pyramids. In the second O site, O(2) is bonded to two equivalent Cd(1) and two equivalent Pb(1) atoms to form OCd2Pb2 trigonal pyramids that share corners with eight equivalent O(1)Cd4Pb trigonal bipyramids, corners with four equivalent O(2)Cd2Pb2 trigonal pyramids, edges with two equivalent O(1)Cd4Pb trigonal bipyramids, and edges with two equivalent O(2)Cd2Pb2 trigonal pyramids.

The corner-sharing octahedral tilt angles range from 52-73°. There is one shorter (2.28 Å) and one longer (2.41 Å) Cd(1)-O(2) bond length. There are two shorter (2.37 Å) and two longer (2.38 Å) Cd(1)-O(1) bond lengths. Pb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form PbO6 octahedra that share corners with eight equivalent Cd(1)O6 pentagonal pyramids, edges with two equivalent Pb(1)O6 octahedra, and edges with four equivalent Cd(1)O6 pentagonal pyramids. Both Pb(1)-O(1) bond lengths are 2.16 Å. All Pb(1)-O(2) bond lengths are 2.21 Å. There are two inequivalent O sites.
