Season 123 - Day 14 of 14

Named after the American architect R. Buckminster _____ for its resemblance to his geodesic domes e.g. "The Montreal Biosphere" this allotrope of carbon was discovered in 1985.
Their molecules consist of carbon atoms that are connected by single or double bonds to form a (partially) closed mesh. Because the form resembles a soccer ball, the molecules are informally called Buckyballs.
What are the names of these molecules? Add "ene" to the last name of the architect and you will have the answer.
