Barium diketonates as precursors for HTSC thin films: structure and properties
Homoligand and mixed ligand barium diketonate complexes have been synthesized and characterized by X-ray structure determination. Homoligand complexes with dipivaloylmethane hexafluoroacetone and pivaloyltrifluoroacetone have oligigomeric or polymeric structure. The mixed complexes with additional anionic ligands (Cl - OH - , Piv - ) form pentanuclear complexes. The structures of the mixed ligand complexes with Lewis bases contain either mono or dinuclear chelates. Deoligomerization is accompanied by a decrease of the sublimation temperature and improves a storage stability of barium complexes used in MOCVD process for production of HTSC films.
