Abstract
Trisbicyclo[2.2.1]heptabenzene 3 crystallizes in space group P2(1)/c w ith cell dimensions a = 5.992 Angstrom, b = 17.288 Angstrom, c = 14.84 3 Angstrom. Mild bond localization is seen in the benzene ring (d(exo( ave))= 1.379 Angstrom; d(endo(ave)) = 1.417 Angstrom) and the annelati on angle C-(ar)-C-(ar)-C-(CH) is constricted to 106.5 degrees. The str ucture supports a bicyclic strain effect on the bond localization in b enzenoid aromatics.
