Abstract
Abstract Bis-2,2,6,6-tetramethylheptane-3,5-dionatolead (1), bis-2,2-dimethyl-6,6,7,7,8,8,8-heptafluorooctane-3,5-dionatolead (2) and bis-1,1,1,5,5,5-hexafluoropentane-2,4-dionatolead (3) have been prepared and characterised. X-ray single crystal structures for (1) and (2) have been determined. Compound (1) has a monomeric structure with the chelating thd (2,2,6,6-tetramethyl-3,5-heptanedione) units distorted away from a stereochemically active lone pair of electrons at the lead (II) centre. The structure of compound (2) is based on unusual dimers. Seven co-ordinate lead units are bridged by the fluorine atoms of the ligand. All three compounds are useful precursors in the deposition of lead-containing materials and their structures are useful in understanding their behaviour in materials deposition.
