The molecule of the title compound, [Pb2(C9H5ClNO)2(C2H3O2)2], lies about a center of inversion. The PbII atom is chelated by acetate and substituted quinolin-8-olate anions; the O atoms of the quinolin-8-olates also bridge to confer a five-coordinate status to each metal center. The geometry approximates a distorted [Psi]-fac octahedron in which one of the sites is occupied by a stereochemically active lone pair.
