The structure of lead molybdenum oxide, Pb5MoO8, has been determined by single-crystal X-ray methods. The crystal structure is a 4:3:2 superstructure of tetragonal α-PbO (litharge), with embodied MoO42− tetrahedra. Infinite double chains of OPb4 tetrahedra are formed. Along these chains, the OPb4 tetrahedra share vertices. Two of the O atoms form three nearly coplanar bonds with Pb atoms.
