A novel cluster compound has been discovered by scientists at Kyoto University. A negative charge is carried by compounds that contain a large metal-oxide cluster. There are many of them, from anti-viral medicines to batteries.
Large, positively charged clusters are what makes the new compound unusual. A small number of positively charged cluster compounds have been found.
A new science can be created by the discovery of new material or molecule. The new positively charged clusters have a lot of potential.
In 1824, the first metal oxide cluster was found. Chemists have created hundreds of compounds with negatively charged clusters, which are useful in a number of areas. Their properties allow them to be used in many different fields.
Scientists have focused on learning the properties of compounds with positive charged clusters.
The positive cluster was found by Kageyama and Abe. Two scientists have been trying to develop new compounds that can absorb visible light. They were trying to replace the chlorine atom with something else.
A new material that was completely different from what we expected was accidentally obtained.
The scientists expected a material that contained 22 atoms. They got a compound with 800 atoms in it.
The scientists were unable to figure out the chemical's structure. When faced with the material's complexity, powder X-ray diffraction failed. After a year, Kageyama thought he could use three-dimensional electron tomography, a cutting-edge electron microscopy technique that has attracted recent attention. The scientists asked Artem Abakumov and Joke Hadermann to help with the structure. The scientists were excited to see the large clusters.
The acidic protons were found in the hydroxyiodide molecule.
According to Kageyama, the finding may open up new possibilities in the design of catalysts.
The work will be published in a journal.
