Alkaline earth metal bismuth containing materials such as Bi2Sr2Ca2Cu2Ox have important applications for electronic thin films. These are prepared by metal organic chemical vapor deposition (MOCVD) using alkaline earth metal and bismuth precursors. Such precursors ideally sublime intact and allow precise stoichiometric control. Currently used MOCVD precursors require relatively high temperatures. In an effort to develop a system that would provide exact stoichiometric control and low deposition temperatures, we aim to develop a heterobimetallic system containing the heavy alkaline earth metal and bismuth in conjunction with the perfluorinated ligand system nonafluoro-tert-butoxide. This system has proven to be advantageous in providing heterobimetallic systems involving alkali/alkaline earth/rare earth metals. In fact, some heterobimetallic compounds bearing this ligand display unprecedented volatility and clean sublimation. We here report on studies to prepare bismuth perfluorinated complexes bearing various co-ligands and combine those with the known alkaline earth analogues to afford the heterobimetallic compounds.
