5-Butyl-5-(2-methyl-1H-inden-1-yl)-5H-dibenzo[b,d]silole

摘要

The structure of the title compound [systematic name: 8-butyl-8-(2-methyl-1H-inden-1-yl)-8-silatri-cyclo-[7.4.0.02,3]trideca-1(13),2,4,6,9,11-hexa-ene], C26H26Si, at 110?K has ortho-rhom-bic (Pbca) symmetry. In the mol-ecule, the butyl group displays an extended conformation with the C—C—C—C torsion angle of 176.8?(2)°. The dihedral angle between the biphenyl group and the indole group is 60.04?(2)°. The structure exhibits a weak intra-molecular C—H?π?inter-action.
