Octafunctionalized iron(II) cage complex with six equivalent methoxyl-terminated alkylsulfide ribbed fragments and two terminal carboxyl groups in its apical aromatic substituents was obtained using nucleophilic substitution of an appropriate hexachloroclathrochelate precursor with an anionic derivative of mercaptoacetic acid; generated in situ in the presence of triethylamine, followed by the further esterification reaction of thus obtained product with methanol. The obtained diamagnetic cage complex was characterized using elemental analysis, MALDI-TOF mass spectrometry, UV-Vis and ¹H NMR spectra, and by the synchrotron single crystal X-ray diffraction experiment as well.
