The number of Kekult structures for primitive coronoids is studied. The systems have obvious counterparts within a class of hydrocarbons known as cycloarenes. Complete solutions are given for centrosymmetrical primitive coronoids and those with trigonal or hexagonal symmetries. The technique is base

It is known that an alternative algorithm to the Gordon-Davidson algorithm for counting the Kekule valence structures of catacondensed non-branched benzenoid hydrocarbons is a reformulation of the original algorithm. Recently an alternative algorithm [ 1,2] to the Gordon-Davison (GD) algorithm [ 31
