title: All-yl(ferrocenylmeth-yl)dimethyl-ammonium perchlorate.
abstract: The asymmetric unit of the title complex, [Fe(C(5)H(5))(C(11)H(17)N)]ClO(4), contains two independent all-yl(ferro-cenyl-meth-yl)dimethyl-ammonium cations and two ClO(4) (-) anions. The anions are disordered each over two sets of sites, with an occupancy ratio of 0.617 (6):0.383 (6). The distances from the Fe atoms to the centroids of the unsubstituted and substituted cyclo-penta-dienyl (Cp) rings are 1.645 (1)/1.657 (1) and 1.644 (1)/1.647 (1) Å. The dihedral angles between the two Cp rings are 2.49 (3) and 1.45 (4)° in the two ferrocenyl groups of the cations.
