Abstract

Ferrocenylmethyl)trimethylammonium iodide (1), [C 14-H20FeN][I], Mr = 385.07, monoclinic, P2dc, a = 8.6236 (5), b = 13.5926 (10), c = 12.8623 (6) A, ~ = 102.792 (4) , V = 1470.3 (2) A 3, Z = 4, T = 293K, F(000) = 760, Dx = 1.74 gcm -3, Mo Ks, A --0.71069 ,~, # = 3.08mm -l, R = 0.024 for 4075 observations [I > 30"(/)]. The [{(CsHs)Fe(CsH4)I-CH2N(CH3)3] + cation is involved in a three-dimensional network of C--H...I-interactions (both the cation and anion residing in general positions). The shortest C.-.I distances are 3.954 (2), 3.992 (2) and 4.009 (3) A. Hexa-Nmethylferrocene-1,1'-diylbis(methylammonium iodide) (2), [C18H30FeN2].2[I], Mr = 584.10, monoclinic, C2/c, a = 27.1457(12), b --12.3446(6), c = 14
