A research group led by Professor Masakazu Saito of Saitama University investigated the properties of compounds synthesized by combining two different metals, and found that the properties of compounds composed of each metal did not appear and completely different physical properties were expressed. discovered.
Since the synthesis of ferrocene (a complex in which an iron atom is sandwiched between two cyclopentadienyl rings) in 1951, a compound in which various transition metals are sandwiched, and a sandwich structure with three layers (triple decker) The compound extended to is synthesized.However, the method of sandwiching two different transition metal atoms in such a triple decker structure has been limited.
The research group has developed a unique ligand that incorporates tin into a carbon π-electron system (the skeleton that occurs in a carbon double bond), and has succeeded in synthesizing a triple-decker complex using this.This time, we succeeded in synthesizing a compound in which two different transition metal atoms (ruthenium and rhodium) are sandwiched using this ligand.When the properties of this compound were investigated, the properties of the compound composed of each metal did not appear, and completely different physical properties were expressed.
This result shows that the combination of two different metal atoms creates properties that are not found in compounds containing each metal atom.In other words, by studying various combinations of metal atoms used, it is possible to create a wide variety of compounds with desired or unexpected properties.
The compound obtained this time was heated in an ionic liquid using microwaves, and we succeeded in synthesizing new nanoparticles composed of three kinds of metals, tin, ruthenium and rhodium.In the future, it is expected to discover a reaction using the generated nanoparticles as a catalyst.
