NIOBIUM 2-ETHYLHEXANOATE DERIVATIVE, PROCESS FOR PRODUCING THE DERIVATIVE, ORGANIC ACID METAL SALT COMPOSITION CONTAINING THE DERIVATIVE, AND PROCESS FOR PRODUCING THIN FILM FROM THE COMPOSITION

摘要

A niobium 2-ethylhexanoate derivative characterized in that it contains niobium in a proportion of 13 to 16 mass% and carbon in a proportion falling within the range of 50 to 58 mass% and consists only of niobium and oxygen atoms and 2-ethylhexyl acid residue. This derivative can be produced by reacting pentakis(alkoxy)niobium with 2-ethylhexyl acid. Further, there is provided an organic acid metal salt composition characterized by containing this derivative, a precursor of metal other than niobium and at least one organic solvent. A thin film containing a niobium element and a non- niobium metal can be produced by coating a base material with the organic acid metal salt composition and heating the same.
