Isomorphous crystals of strychninium 4-chlorobenzoate and strychninium 4-nitrobenzoate

A. Bialonska and Z. Ciunik

Abstract: In strychninium 4-chlorobenzoate, C₂₁H₂₃N₂O₂⁺·C₇H₄ClO₂^-, (I), and strychninium 4-nitrobenzoate, C₂₁H₂₃N₂O₂⁺·C₇H₄NO₄^-, (II), the strychninium cations form pillars stabilized by C-HO and C-H [pi] hydrogen bonds. Channels between the pillars are occupied by anions linked to one another by C-H [pi] hydrogen bonds. The cations and anions are linked by ionic N-H⁺O^- and C-HX hydrogen bonds, where X = O, [pi] and Cl in (I), and O and [pi] in (II).

Formula: C₂₁H₂₃N₂O₂⁺·C₇H₄ClO₂^- and C₂₁H₂₃N₂O₂⁺·C₇H₄NO₄^-
