The title compound, [Fe(C5H5)(C18H32N)], was synthesized by
the amination of ferrocenecarbaldehyde. In the complex, the two cyclopentadienyl (Cp) rings are almost parallel with a dihedral angle of 1.36 (8), and are separated by a centroid–
centroid distance of 3.299 (2) A˚ . In the crystal, adjacent molecules are linked into a one-dimensional supramolecular structureviaweak C—H interactions between the Cp ring H atom and the Cp ring.

S1. Comment
The high lipophilicity and electrochemical behaviour of ferrocene render it very attractive for drug design. The
incorporation of a ferrocenyl moiety into the 'standard′ drug offers new possibilities in therapeutic applications and
reversal of drug resistances (Atteke et al., 2003; Baramee et al., 2006). On the other hand, the linear compounds derived
from ferrocene have shown great useful functions in supramolecular chemisty (Zhang et al., 2010). In this paper, we
report the synthesis and crystal structure of the title compound.
As shown in Fig. 1, the title compound has a tadpole-typed molecular configuration. The planes of two
cyclo-pentadienyl (Cp) rings in the ferrocene scaffold are approximately parallel with a centroid–centroid distance of 3.299 (2)
Å and a dihedral angle of 1.36 (8)°. The Fe—C bond distances are in the range of 2.0295 (18) to 2.0502 (16) Å (Table 1),
which are consistent with those data in the similar compounds previously reported (Zheng & Liu, 2009). The adjacent
molecules are linked by weak C—H···π interactions between ferrocene cores (Table 2), forming a one-dimensional
supramolecular architecture as shown in Fig. 2.
S2. Experimental
A mixture of ferrocenecarbaldehyde (2.415 g, 0.01 mol) and lauryl amine (0.08 mol) in anhydrous methanol (50 ml) was
stirred and kept refluxing for 12 h under a nitrogen atmosphere in dark place. NaBH4 (0.110 g, 2.9 mmol) was added in
small portions. The mixture was stirred for 15 h, and 10 ml acetone was added to stop the reaction. The mixture was
extracted with CH2Cl2 (30 ml) 10 min later. The combined organic phase was dried with anhydrous Na2SO4, and then
evaporated in vacuo. The residue was purified by silica gel column chromatography (eluent, petroleum ether : ethyl
acetate = 5:1 by volume) to give the title compound as yellow powder (yield 1.545 g, 80.7%). Single crystals were grown
in a mixed solution of hexane/ethyl acetate (2:1 by volume) at room temperature.
S3. Refinement
H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.98 (CH), 0.97 (CH2) and 0.96 (CH3)
