The structure of the [Rh2C3]+ ion and its reaction with CH4 in the gas phase have been
studied by infrared photodissociation spectroscopy and mass spectrometry in conjunction …

Although the field of metal-to-metal multiple bonding has been considered as mature, it was
recently reinvigorated by the discovery of quintuple bonded dinuclear complexes. Initiated …

Transition metal complexes that exhibit multiple metal–metal bonding are of fundamental
importance in chemistry.[1a] Following decades of intense scrutiny of double, triple, and …

Although quadruple bonding in transition-metal chemistry has been considered a thoroughly
studied area,[1a] the concept of multiple bonding [1b] was reinvigorated in 2005 by the …
