The material described by PtPd3Bi2O8 crystallizes in the triclinic P-1 space group. Pt(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(4) atoms. In the second Pd site, Pd(2) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(3) atoms. In the third Pd site, Pd(3) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(4) atoms. Bi(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Pt(1), one Pd(1), one Pd(2), and one Bi(1) atom to form distorted OBiPd2Pt tetrahedra that share corners with two equivalent O(4)Bi2Pd2 tetrahedra, corners with two equivalent O(2)Bi2PdPt tetrahedra, corners with three equivalent O(1)BiPd2Pt tetrahedra, corners with four equivalent O(3)Bi2PdPt tetrahedra,  an edgeedge with one O(4)Bi2Pd2 tetrahedra,  an edgeedge with one O(2)Bi2PdPt tetrahedra, and  an edgeedge with one O(3)Bi2PdPt tetrahedra. In the second O site, O(2) is bonded to one Pt(1), one Pd(3), and two equivalent Bi(1) atoms to form distorted OBi2PdPt tetrahedra that share corners with two equivalent O(2)Bi2PdPt tetrahedra, corners with two equivalent O(1)BiPd2Pt tetrahedra, corners with four equivalent O(4)Bi2Pd2 tetrahedra, corners with four equivalent O(3)Bi2PdPt tetrahedra,  an edgeedge with one O(4)Bi2Pd2 tetrahedra,  an edgeedge with one O(2)Bi2PdPt tetrahedra,  an edgeedge with one O(3)Bi2PdPt tetrahedra, and  an edgeedge with one O(1)BiPd2Pt tetrahedra. In the third O site, O(3) is bonded to one Pt(1), one Pd(2), and two equivalent Bi(1) atoms to form OBi2PdPt tetrahedra that share corners with two equivalent O(3)Bi2PdPt tetrahedra, corners with four equivalent O(4)Bi2Pd2 tetrahedra, corners with four equivalent O(2)Bi2PdPt tetrahedra, corners with four equivalent O(1)BiPd2Pt tetrahedra,  an edgeedge with one O(2)Bi2PdPt tetrahedra,  an edgeedge with one O(3)Bi2PdPt tetrahedra, and  an edgeedge with one O(1)BiPd2Pt tetrahedra. In the fourth O site, O(4) is bonded to one Pd(1), one Pd(3), and two equivalent Bi(1) atoms to form distorted OBi2Pd2 tetrahedra that share corners with two equivalent O(4)Bi2Pd2 tetrahedra, corners with two equivalent O(1)BiPd2Pt tetrahedra, corners with four equivalent O(2)Bi2PdPt tetrahedra, corners with four equivalent O(3)Bi2PdPt tetrahedra,  an edgeedge with one O(4)Bi2Pd2 tetrahedra,  an edgeedge with one O(2)Bi2PdPt tetrahedra, and  an edgeedge with one O(1)BiPd2Pt tetrahedra. is represented by the CIF file [CIF]
