The dual in the crown : The same compound can adopt two different, non‐equilibrium tautomeric structures. This unique structural dualism is demonstrated by the isolation of pure tautomeric pairs, 7‐RR′NH‐7,8,9‐C 3 B 8 H 10 (zwitterionic) and 7‐RR′N‐7,8,9‐C 3 B 8 H 11 (neutral) (where R,R′=H or alkyls, see scheme, PNT=proton nontransferring, PT=proton transferring) in the tricarbollide series.
