1 Source of materials

The 3-methylthiophene-2-carbaldehyde (2.77 g, 22.0 mmol), acetylferrocene (2.28 g, 10.0 mmol) and KOH (0.67 g, 12.0 mmol) were added to the mortar. After stirring well, the reaction mixture was ground for 20 min, until the TLC indicated the reaction was completed, then diluted with water and filtered. The solid was collected and washed with water, and dried overnight under vacuum. The crude product was further purified by flash silica chromatography. For crystal growth, the crude product was dissolved in a minimal amount of hot ethanol and slowly cooled to room temperature (Tables 1 and 2).

2 Experimental details

Single-crystal X-ray diffraction data were collected at 170 K on a Bruker D8 Venture diffractometer. 1 The structure was solved using Shelx-2014 2 and refined with anisotropic refinement for non-hydrogen atoms. 3 Hydrogen atoms were placed in idealized positions and refined with a riding model. All calculations were performed in Olex2, confirming the data and structural model quality. 4

3 Comment

The synthesis and structural characterization of organometallic compounds, particularly those containing ferrocenyl motifs, have attracted significant attention due to their unique electronic properties, chemical versatility, and wide-ranging applications in materials science, catalysis, and medicinal chemistry. 5 Among these, α,β-unsaturated carbonyl compounds incorporating ferrocenyl units are of special interest due to their conjugated systems, which enable enhanced charge delocalization and electron transfer. 6 , 7 , 8 , 9 , 10 , 11 In this context, the single-crystal structure of (E)-(3-(3-methylthiophen-2-yl) acryloyl)ferrocene provides essential insights into the molecular geometry and intermolecular interactions.

The single-crystal structure of (E)-(3-(3-methylthiophen-2-yl)acryloyl) ferrocene was determined, revealing a well-defined molecular geometry. The ferrocene core adopts a typical sandwich structure with the Fe atom situated between two nearly parallel cyclopentadienyl (Cp) rings, 12 , 13 , 14 exhibiting minimal distortion and dihedral angle 1.24°. The ferrocenyl unit is connected to the (E)-acryloyl group through a single bond at the Cp ring, maintaining planarity in the conjugated system. 15

The (E)-acryloyl group displays an E-configuration around the C=C bond, ensuring efficient π-conjugation along the molecule. The acryl group is further linked to the 3-methylthiophen-2-yl moiety. The thiophene ring, containing the sulfur atom, exhibits slight deviation from coplanarity with the acryl chain, likely due to steric interactions caused by the methyl substituent. The Fe–C bond distances are consistent with those typically observed in ferrocene derivatives, and the bond angles within the acryl-thiophene system, which suggest effective conjugation and rigidity of the structure.

This structure provides valuable insight into the electronic and steric properties of ferrocenyl-acryloyl-thiophene compounds.
