## Abstract The X‐ray crystal structure of 1__H__‐pyrazole‐3‐(__N‐tert__‐butyl)‐carboxamide was determined. In the solid state, the ^13^C and ^15^N CP/MAS NMR spectra correspond to this tautomer. In solution, both tautomers are present in a ratio that depends on the temperature (at 293 K, 90% 3‐sub
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 (show
