The syntheses and molecular structures, as determined by single-crystal X-ray diffraction analysis, of the first intramolecularly [4+2]-coordinated tetraorganolead compound {4-t-Bu-2,6-[P(O)(OEt)2]2C6H 2}PbPh3 (2) and the triphenyllead chloride adduct of the first intramolecularly coordinated benzoxaphosphaplumbole {[1(Pb),3(P)-Pb(Ph)2OP(O)(OEt)-5-t-Bu-7-P(O)-(OEt)2]C 6H2·Ph3PbCl} (3a) are reported. The reaction of 2 with [Ph3C]+ [PF6]- and p-MeC6H4SO3H, respectively, provides the triorganolead salts {4-t-Bu-2,6-[P(O)(OEt)2]2C6H2} PbPh2+X- (4, X = PF6; 4a, X = p-MeC6H4SO3). Reaction of 2 with bromine and hydrogen chloride, respectively, gives the diorganolead dihalides {4-t-Bu-2,6-[P(O)(OEt)2]2C6H2} PbPhX2 (5, X = Br; 6, X = Cl).
