Abstract The new bicyclic lead (II) phosphinate [(t-Bu) 2PO2] 2Pb (1) was synthesized by the reaction of p-tolyllead triacetate with di-t-butylphosphinic acid and water. An X-ray study showed that it had a pseudo-trigonal bipyramidal geometry (p-TBP) with a stereochemically active lone pair of electrons occupying an equatorial site. Infrared data ruled out the possible presence of a Pb [sbnd] H bond. A series of new monocyclic Pb (IV) compounds,[Et4N][( ...
