The compound is the prototypical antiaromatic hydrocarbon with 4 π-electrons. It is the smallest [n]-annulene ([4]-annulene). Its rectangular structure is the result of the Jahn–Teller effect, which distorts the molecule and lowers its symmetry, converting the triplet to a singlet ground state. The electronic states of cyclobutadiene have been explored with a variety of computational methods. The rectangular structure is consistent with the existence of two different 1,2-dideutero-1,3-cyclo…
