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 φ (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.
