The title compound, {[(C5H5)9Pb 4]-[(C5H5)5Pb 2]-[Li(12-crown-4)2]+2} 1, is synthesised by the reaction of [(C5H5) 2Pb] and [(C5H5)Li] and 12-crown-4 (3:1:2 equiv.), and is shown by X-ray diffraction to contain both a quintuple-decker and a triple-decker sandwich anion; in contrast, the corresponding reaction with [(C5H5)2Sn] (which possesses no such polymeric lattice of its own) in place of [(C5H5) 2Pb] yields the simple 'paddlewheel' molecule {[(C5H5)3Sn]-[Li(12-crown-4) 2]+}2.
