摘要:Diammonium ruthenium diethylenetriaminepentaacetate represented by formula (1) or hydrate thereof, which are water-soluble and excellent in handling and exhibit such high stability both in the air and in an aqueous solution as to withstand long-term storage. These novel compounds are useful as the catalyst for the synthesis of ammonia, the hydrogenation catalyst for carbonyl compounds or aromatic compounds, the raw material for the production of ruthenium-base metal oxide ceramics, and so on.
