The crystal structure described by PbPt2O4 crystallizes in the triclinic P-1 space group. There are four inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. In the second Pt site, Pt(2) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. In the third Pt site, Pt(3) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(4) atoms. In the fourth Pt site, Pt(4) is bonded in a distorted square co-planar geometry to two equivalent O(1) and two equivalent O(4) atoms. Pb(1) is bonded in a 7-coordinate geometry to one O(4), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Pt(1), one Pt(4), and two equivalent Pb(1) atoms to form distorted OPt2Pb2 tetrahedra that share corners with two equivalent O(1)Pt2Pb2 tetrahedra, corners with four equivalent O(3)Pt2Pb2 tetrahedra, corners with four equivalent O(4)Pt3Pb tetrahedra,  an edgeedge with one O(1)Pt2Pb2 tetrahedra,  an edgeedge with one O(3)Pt2Pb2 tetrahedra, and  an edgeedge with one O(4)Pt3Pb tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Pt(2), one Pt(3), and two equivalent Pb(1) atoms. In the third O site, O(3) is bonded to one Pt(1), one Pt(2), and two equivalent Pb(1) atoms to form distorted OPt2Pb2 tetrahedra that share corners with two equivalent O(3)Pt2Pb2 tetrahedra, corners with two equivalent O(4)Pt3Pb tetrahedra, corners with four equivalent O(1)Pt2Pb2 tetrahedra,  an edgeedge with one O(1)Pt2Pb2 tetrahedra,  an edgeedge with one O(3)Pt2Pb2 tetrahedra, and  an edgeedge with one O(4)Pt3Pb tetrahedra. In the fourth O site, O(4) is bonded to one Pt(1), one Pt(3), one Pt(4), and one Pb(1) atom to form distorted OPt3Pb tetrahedra that share corners with two equivalent O(3)Pt2Pb2 tetrahedra, corners with three equivalent O(4)Pt3Pb tetrahedra, corners with four equivalent O(1)Pt2Pb2 tetrahedra,  an edgeedge with one O(1)Pt2Pb2 tetrahedra, and  an edgeedge with one O(3)Pt2Pb2 tetrahedra. is represented by the CIF card [CIF]
