The compound described by MgCrPbO3 crystallizes in the tetragonal P4/mmm space group. Mg(1) is bonded in a square co-planar geometry to two equivalent Pb(1) and four equivalent O(2) atoms. Cr(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. Pb(1) is bonded to two equivalent Mg(1) and four equivalent O(1) atoms to form a mixture of edge and corner-sharing PbMg2O4 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to four equivalent Pb(1) atoms. In the second O site, O(2) is bonded in a square co-planar geometry to two equivalent Mg(1) and two equivalent Cr(1) atoms. is represented by the CIF card [CIF]
