The reactions of SmI₂(THF)₂ and YbI₂(THF)₂ with the alkali-metal salts of 2,5-dimethylpyrrole, or the reaction of SmCl₃(THF)₃ and YbCl₃(THF)₃ with the same ligands followed by reduction with the appropriate alkali metals, led to the formation of divalent mono- and polynuclear complexes. Structural analysis of these complexes indicated that the bonding mode adopted by the ligand depends on the nature of the alkali-metal cation retained in the structure.
