Fulvene (pentafulvene) is a hydrocarbon with the formula (CH=CH)
2C=CH
2. It is a prototype of a cross-conjugated hydrocarbon. Fulvene is rarely encountered,
but substituted derivatives (
fulvenes) are numerous. They are mainly of interest as
ligand
In coordination chemistry, a ligand is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's electr ...
