摘要

PROBLEM TO BE SOLVED: To provide a solution composition consisting of a metal complex being coordinated with two kinds of ligands, a solution composition for producing a superconductive film, an amorphous solid of the metal complex, a method for producing a solution containing the metal complex, and a method for producing a solution for producing a superconductive film of rare earths. SOLUTION: A solution composition comprising a homogeneous solution obtained by dissolving a metal complex in a solvent, wherein the metal complex is formed by coordinating with two kinds of ligands consisting of a group selected from a trifluoroacetic acid group or a pentafluoropropionic acid group, and pyridine group onto metal ions of metal species containing rare earths elements, barium and cupper, a solution composition for producing a superconductive film of rare earths, an amorphous solid of a specific metal complex, a method for producing a solution containing a metal complex coordinated with specific ligands onto specific metal species, and a method for producing a solution for producing a superconductive film of rare earths are provided.
