First report of a system containing a ruthenium atom that takes part in two different types of aromaticity simultaneously

Scientists have made a heteronuclear complex containing a ruthenium atom that takes part in two different aromatic systems. This exotic molecule is surprisingly stable. In fact, it’s so stable that it can be bottled and stored.
