Abstract
The authors current studies are directed toward single-source anhydrous volatile molecular barium CVD precursors for use in synthesizing electroceramic metal oxides. To this end, the authors have utilized the crystalline, hydrocarbon-soluble metal ethoxide [Ba-(OEt)[sub 2](HOEt)[sub 4]][sub [infinity]]. They have observed a facile reaction with this alkoxide and a variety of [beta]-diketonate ligands in n-hexane at room temperature to yield a range of barium complexes, [Ba([beta]-diket)[sub 2]][sub [infinity]] [where [beta]-diket = acac (CH[sub 3]COCHCOCH[sub 3]), Ph[sub 2]acac (PhCOCHCOPh), tfa (CF[sub 3]COCHCOCH[sub 3]), hfa (CF[sub 3]-COCHCOCF[sub 3]), and thd ([sup t]BuCOHCOBu[sup t])], analogous to the reactions of transition metal alkoxides. The authors report here a synthetic rout to complexes of the type [M(diket)[sub n](L-L)][M = Ba, diket is tfa, and L-L is Hmteta (1); M = Y, diket is thd, and L-L is diglyme (2)].
