Abstract Protonation of Fe(η 5-C5H5)[(η 5-C5H4)(2-C5H4N)]1 in 98% H2SO4 followed by dilution with water and addition of NaBF4 yields Fe(η 5-C5H5)[(η 5-C5H4)(2-C5H4NH+)](BF 4 − )2 instead of a ferrocinium derivative. Complex2 crystallizes in the monoclinic system, P21 /a∶:a=7.984(1),b=9.981(2),c=18.220(4) Å,β=102.31 (1)°,V=1418.5 Å3,Z=4. The pyridinium ring makes a dihedral angle of 21.0(2)° with the cyclopentadienyl ring to which it is bound. One F atom of BF 4 − is involved in short van der Walls contacts with the N (2.764(5) Å) and the H (2.08(6) Å) atoms of the NH+ moiety.
