Distribution of the two C—I+⋯electron donor angles (°) versus XB distances for CCDC structures containing the C—I+—C moiety. The analysis has been made using the Cambridge Structure Database (CSD, Version 5.37, November 2015, including updates until February 2016). Blue dots and red squares are the two angles associated with any XB; for bi-, trifurcated XBs, the most linear was selected. The mean value of the C—I+—C angle in the considered structures is 94.08°; the clustering of the C—I+⋯electron donor angles around 90° and 170° is indicative of their preferential linearity.
