guanidinate complexes [Pb(CyG)Cl]23, and [Pb(HDG)Cl]24 in moderate yields. The complexes are thermally stable, 2, 3 and 4 decompose between 163–202 °C whilst 1 melts with decomposition to lead metal at 310 °C. 2, 3 and 4 are unsymmetrical dimers in the solid state but their NMR data suggested fluxional behaviour in solution.
