The 1:1–2:1 reaction of [2,6-(iPrO)2C6H3]Li with anhydrous SmCl3 in THF gave [2,6-(iPrO)2C6H3]3 Sm 1 exclusively, while the 3:1 reaction gave [2,6-(iPrO)2C6H3]4SmLi 2 as major product, which crystallizes in the monoclinic space group C2/c(No. 15) with a=47.52(1) Å, b=11.680(9) Å, c=18.862(9) Å, β=112.19(3)°, V=9694(8) Å3, Z=8, R=0.077 and Rw=0.074. In a similar manner, [2,6-(iPrO)2C6H3]3La was obtained
