Energy-framework diagrams for Eele, Edis and Etot for a cluster of molecules in 1,1′-di­methylferrocene (CSD refcode ZAYDUY02). The ferrocene `dimer' proposed by Bogdanović & Novaković (2011BB6) is the vertical pair of molecules, with an Fe⋯Fe distance of 5.709 Å. All diagrams use the same cylinder scale of 150 for energies.
