N-Phenethylbiguanidium tetrachlorozincate(II)

M. Zhu, P. Yang and L. Lu

Abstract: The title compound, (C₁₀H₁₇N₅)[ZnCl₄], was crystallized from an aqueous solution (pH 2) containing a 1:1 molar ratio of ZnCl₂ and 1-phenethylbiguanide hydrochloride. The geometry of the tetrachlorozincate(II) anion is a slightly distorted tetrahedron. The N-phenethylbiguanidium divalent cation is diprotonated at the two imino groups, resulting in an intramolecular N-HN hydrogen bond, which stabilizes the conformation of the cation in the structure. The dihedral angle between the two guanidine groups is 48.7  (2)°.
