Abstract

The synthesis and characterization of thermally stable, volatile, group 2 element-containing complexes is an important prerequisite for the subsequent use of these compounds in chemical vapor deposition (CVD) of superconducting metal oxides (SMO) and other electronic materials, e.g., YBa2Cu3O7-δ. and CaGa2S4:Ce. The utilization of group 2 metal ethoxide compounds {[M(OEt)2(EtOH)4]n (where M = Ca, Sr or Ba)) as precursors to additional complexes is discussed. For example, the compounds [M(tmhd)(OEt)(EtOH)]n (Htmhd = 2,2,6,6- tetramethylheptane-3,5-dione) may be obtained by reacting one equivalent of Htmhd with the metal bis(ethoxide), and these also may be reacted further with functionalized alcohols, or a second β–diketone, to form heteroleptic compounds. Additionally, the preparation and characterization of some Lewis base adducted complexes have been examined with an emphasis on the role that water plays in their isolation.
