The first 1,1′-digallylferrocene and a rodlike, polymeric donor-acceptor complex:: Synthesis, properties, and structure of [Fe(η5-C5H4GaMe2)2]n and [Fe(η5-C5H4GaMe2)2(C12H8N2)]n

The reaction of 1,1'-bis(trichlorostannyl)ferrocene with trimethylgallium results in the formation of Fe(C5H4GaMe2)(2) (1), the first digallylferrocene. An X-ray crystal structure analysis of 1 reveals a polymeric structure. NMR data confirm a monomeric structure of [1(.)2 donor] in donor solvents. The reaction of 1 with phenazine results in the formation of the supramolecular polyferrocene [1(.)phenazine](n). Its rodlike structure is proven by X-ray crystallography.
