Crystal structure of N-butyl-2,3-bis­(di­cyclo­hexyl­amino)­cyclo­propeniminium chloride benzene monosolvate

N-Butyl-2,3-bis­(di­cyclo­hexyl­amino)­cyclo­propenimine (1) crystallizes from benzene and hexa­nes in the presence of HCl as a mono­benzene solvate of the hydro­chloride salt, [1H]Cl·C(6)H(6) or C(31)H(54)N(3) (+)·Cl(−)·C(6)H(6), in the P2(1)/n space group. The protonation of 1 results in the generation of an aromatic structure based upon the delocalization of the cyclo­propene double bond around the cyclo­propene ring, giving three inter­mediate C—C bond lengths of ∼1.41 Å, and the delocalization of the imine-type C—N double bond, giving three inter­mediate C—N bond lengths of ∼1.32 Å. Ion–ion and ion–benzene packing inter­actions are described and illustrated.
