Popis:	The standard enthalpies of formation of some lead(II) β-diketonates: Pb(aa) 2 ; Pb(dpm) 2 ; Pb(zis) 2 ; Pb(pta) 2 ; and Pb(hfa) 2 (where aa = pentane-2,4-dionate, dpm = 2,2,6,6-tetramethylheptane-3,5-dionate, zis = 2-methoxy-2,6,6-trimethylheptane-3,5-dionate, pta = 1,1,1-trifluoro-5,5-dimethylhexane-2,4-dionate, and hfa = 1,1,1,6,6,6-hexafluoropentane-2,4-dionate) were determined by solution-reaction calorimetry measurements. The corresponding sublimation enthalpies of the complexes were derived from measurements of saturated vapour pressure by means of the flow method. The homolytic 〈DH R 〉(PbO) and heterolytic 〈DH I 〉(PbO) bond dissociation enthalpies were hence derived.
