Abstract

X-ray investigation of 3-butoxy-4-(1,3,3-trimethyl-2,3-dihydro-1H-2-indolylidenemethyl)-3-cyclobutene-1,2-dione and its thio analog has been carried out. Replacement of the carbonyl oxygen atom by a sulfur atom causes electron density delocalization and equalization of the C-C bonds between the four-and five-membered rings.
