The reactions of Ln(AlMe4)3 (Ln=Ho, Tm) with the crown ether [12]crown-4 yield dicationic methyl rare-earth metal complexes [LnMe([12]crown-4)2][AlMe4]2 (Ln=Ho (1), Tm (2)). The reaction of La(AlMe4)3 with [18]crown-6 in thf affords [LaMe([18]crown-6)(thf)2][AlMe4]2 (3). The compounds have been characterized by X-ray diffraction, 1 and 3 additionally by elemental analyses as well as by 1H and 27Al, and 3 also by 13C NMR spectroscopy
