The dinuclear title compound, [Pb2(C10H6NO2)2(CH3COO)2(CH3OH)2], lies across an inversion center. The methanol-coordinated PbII atom is chelated by the acetate anion as well as by the quinoline-2-carboxylate anion. One O atom of the quinoline-2-carboxylate anion bridges two symmetry-related PbII atoms, forming the dinuclear compound. Aside from the six atoms connected to the PbII atom by regular coordination bonds, the structure features a long Pb...O interaction [3.145 (3) Å] that gives rise to a distorted [Psi]-square-antiprismatic geometry at the metal center. The H atom of the methanol is hydrogen bonded to an O atom of the acetate.
