✦ Synopsis

A careful deformation density study of tetrafluoroterephthalodinitrile at 98K has been made from X‐ray diffraction measurements. Prominent ‘bonding density’ peaks are found at or near the mid‐points of the C, C‐ and C, N‐bonds but not for the C, F‐bonds, which show only weak density. Similarly weak bonding densities for C, F‐bonds are also found for 1, 1, 4, 4‐tetrafluorocyclohexane. The possible significance of these results in terms of bonding theory is briefly discussed.

Bent bonds in the strained fullerene system, restricted to the [5,6] bonds, were detected by high-resolution X-ray structure analysis of the 1,2-dihydro[60]fullerene derivative 1. In addition the maxima of electron densities are higher in the [6,6] bonds than in the [5,6] bonds-an important finding
