✦ Synopsis

5,5 0 -Diethoxy-3,3 0 -methanediyl-bis-indole 1 was synthesized by novel protocol and its solid state structure was analyzed using X-ray diffraction and 13 C CP/MAS NMR methods. Double resonances were observed in the spectrum of 1, and different structure of both indole systems in one molecule (shown by X-ray studies) is responsible for this spectral pattern. In the crystal only one intermolecular hydrogen bond (N1-H1Á Á ÁO11 0 ) was revealed, which is uncommon among bis-indole derivatives.
