Quintuple bond

A quintuple bond is a type of chemical bond involving the sharing of five pairs of electrons between two atoms. This means that there are five single bonds worth of electron pairs being shared. Quintuple bonds are relatively rare and most commonly observed in certain transition metal complexes, especially those involving heavier transition metals. In terms of examples, compounds like some metal carbides may exhibit quintuple bonds, such as in the case of the carbon-carbon bond found in certain metal systems.
