9-Ethyl-3,6-diformyl-9H-carbazole

Abstract

The structure of the title compound, C16H13NO2, was determined as a part of a project on the synthesis of new compounds which can make two-photon absorptions. In the crystal structure, both aldehyde groups are located within the carbazole plane. One of these groups is disordered and was refined using a split model with site-occupation factors for each position of 0.5.
