Guanidinium 4-amino-benzoate.

Pereira Silva PS, Ramos Silva M, Paixão JA, Matos Beja A - Acta Crystallogr Sect E Struct Rep Online (2010)

Bottom Line: The 4-amino-benzoate anion is almost in a planar conformation with a maximum deviation of 0.024 (2) Å for the N atom.The bond length in the deprotonated carboxyl group is inter-mediate between those of normal single and double Csp(2)=O bonds, indicating delocalization of the charge over both O atoms of the COO(-) group.This structure is very similar to that of guanidinium benzoate.

ABSTRACT
In the title compound, CH(6)N(3) (+)·C(7)H(6)NO(2) (-), the cation and anion lie on crystallographic mirror planes. The 4-amino-benzoate anion is almost in a planar conformation with a maximum deviation of 0.024 (2) Å for the N atom. The bond length in the deprotonated carboxyl group is inter-mediate between those of normal single and double Csp(2)=O bonds, indicating delocalization of the charge over both O atoms of the COO(-) group. In the crystal, N-H⋯O hydrogen bonds assemble the ions in layers propagating in the bc plane. This structure is very similar to that of guanidinium benzoate.
