Abstract
The structure of the title salt, (C5H7N2)[Fe(C6H4O2)(C6H5O2)], consists of 3-Aminopyridinium cations and 1′-carboxyferrocene-1-carboxylate monoanions. The ferrocenyl moiety of the anion adopts a typical sandwich structure, with Fe-C distances in the range 2.0270 (15)-2.0568 (17) Å. The anion possesses an eclipsed conformation, with the torsion angle (Csubst-Cpcent-Cpcent-Csubst) equal to 66.0°. The conformations of other 1′-carboxyferrocene-1-carboxylate monoanions are compared and analyzed on the basis of literature data.
