X-ray diffraction study of polycrystals and films of lead (II) hexafluoroacetyl acetonate and pivaloyltrifluoroacetyl acetonate

Volatile Lead β-Diketonates as CVD Precursors

“…[5] Crystal structures have been determined for several compounds. [6][7][8] By means of complex thermal analysis within the temperature range 25-500°C, a study of the thermal stability of the obtained compounds in helium and in oxygen has been carried out. The major solid product of the thermolysis of complexes with aliphatic substituents in the ligands is lead(II) oxide in the forms of α-and β-modifications, while fluorine-containing complexes give β-PbF 2 .…”

“…2) are explained by additive intermolecular coordination in the crystal structure, which is determined for each complex by the nature of the substituents in the ligand. [6][7][8] On the basis of the data obtained on the thermal properties of chelates, we chose the following compounds to be used for the preparation of lead-containing films: Pb(dpm) 2 , Pb(zis) 2 , Pb(pta) 2 , Pb(hfa) 2 . We also determined the deposition conditions for the preparation of coatings.…”

On THE CRYSTAL STRUCTURE AND SOME STRUCTUREDEPENDENT PROPERTIES OF LEAD(II) Β-Diketonates

“…The X-ray diffractometry data for Pb(hfa)2 have been listed in [2]. The crystal structure of Pb(hfa)2 ( Fig.…”

“…The crystal structure of Pb(ttf) 2 As for other fluorine-containing lead(ll) ß-diketonates, the crystal structure of Pb(ttf) 2 is composed of the chains of complex molecules (Fig. 5).…”

“…The next members of the volatility row are fluorine-free complexes Pb(dpm) 2 and Pb(aa) 2 . High volatility of Pb(dpm) 2 is explained by the non-polymeric structure in the crystal.…”
