摘要：

Hydrocarbon-soluble Group IIA metal ethoxides [{M(OEt)2(EtOH)4}n] (M = Sr or Ba) react with the beta-diketonate 2,2,6,6-tetramethylheptane-3,5-dionate (Htmhd) to yield the volatile complexes [Sr3(tmhd)6(Htmhd)] and [Ba4(tmhd)8] in excellent yield. These materials have been studied by classical spectroscopic techniques, differential scanning calorimetry and thermogravimetric analysis. They have also been characterised by single-crystal X-ray diffraction at 150 K, and shown to exist as a trimer and tetramer respectively, the former also incorporating a neutral Htmhd ligand.
