title: (Ferrocenylmeth-yl)trimethyl-ammonium perchlorate.
abstract: The asymmetric unit of the title complex, [Fe(C(5)H(5))(C(9)H(15)N)]ClO(4), contains one discrete (ferrocenylmeth-yl)trimethyl-ammonium cation and one perchlorate anion. The anion is disordered over two sets of sites, with refined occupancies of 0.776 (8) and 0.224 (8). The distances from the Fe atom to the centroids of the unsubstituted and substituted cyclo-penta-dienyl (Cp) rings are 1.650 (1) and 1.640 (1) Å, respectively. The Cp rings form a dihedral angle of 2.66 (3)°.
