Electron density distribution in the bonds and nonbonded contacts of a bicyclo[1.1.1]pentane derivative
Abstract
The difference electron density along the very short C ⋯ C contact (1.9226 Å) of the bicyclo[1.1.1.]pentane(1) determined by low-temperature (100K)X-ray structure ananlysis is negative, and comparison is made with the [1.1.1.]propellane system recently published; the bicyclo[1.1.1.]pentane bonds are bent by about 10°.
