2-{[2-(Piperazin-4-ium-1-yl)ethyl-iminio]meth-yl}phenolate 0.06-chloride 0.94-perchlorate
Abstract:
The structure of the title salt, C(13)H(20)N(3)O(+)·0.94ClO(4) (-)·0.06Cl(-), contains a zwitterionic Schiff base with a net positive charge and a perchlorate anion having substitutional disorder with Cl. In the cation, the azomethine N atom is protonated and donates hydrogen bonds to the phenolate O atom and to the tertiary N atom of the piperazine ring. In the crystal, two Schiff base mol-ecules are linked about a center of inversion by a pair of N-H⋯O hydrogen bonds. The resulting dimers are N-H⋯O and C-H⋯O hydrogen bonded to the perchlorate anions, forming a three-dimensional structure. The network is further consolidated by C-H⋯π inter-actions.
