Methyl 4-(1'-carboxyferrocen-1-yl)butyrate.
The title compound, [Fe(C6H5O2)(C10H13O2)], contains a heteroannularly substituted ferrocene unit, with the two substituents, viz. 3-(methoxycarbonyl)propyl and carboxyl, both capable of forming O-H...O hydrogen bonds. The keto ester group is stereochemically hindered by the trimethylene spacer and does not participate in intramolecular hydrogen-bond formation. Instead, the carboxy groups form self-complementary intermolecular hydrogen bonds [O...O = 2.650 (2) A], which join the molecules into centrosymmetric dimers with a graph-set descriptor R(2)2(8).
