Figure 3
A plot of the geometric parameters for truxinic-type cyclo­butanes with formula C4H4R2R2 retrieved from the CSD. Each red ball corresponds to one cyclo­butane ring in the three-dimensional space defined by the average of four bond lengths, the average of four bond angles, and the average of the absolute values of the four torsion angles in the cycle. This distribution is also projected on three two-dimensional spaces, for each couple of geometric parameters (magenta, green, and blue dots). The parameters for the title compound are represented with black dots.
