133.9(6) pm; this is the length of the shortest BC bond known so far. It was found in 1 and confirms the importance of the resonance structure A. But the resonance structure B is also important for the description of 1 , as follows from the length of the second BC bond, which is markedly shorter than that of a BC single bond. Together, both observations underscore the electronic similarity of 1 and the propargyl/allyl cation.
