Abstract :
Synthesis and structural analysis of 1,2-bis(o-carboranyl)benzene were performed to examine the steric effects of the two extremely bulky o-carborane cages at adjacent positions on the planarity of the benzene ring. X-ray crystallographic analysis supported by DFT calculations revealed that the benzene ring is significantly deformed by the bulky o-carboranyl groups.
