Resumo

Interaction of SmI2 with C5H3Bu2tNa and C5H4ButNa yielded a monosolvate (I) with the formula (η5-C5H3Bu2t)2Sm · OC4H8 and a homoleptic ate complex (II) with the formula [NaSm(η5:η2-C5H4But)3 · OC4H8]n. The crystals of I are monoclinic: a 11.449(3); b 15.305(4); c 17.688(5) Å; γ 92.93(2)°; space group P21/n; Z = 4; dcalcd 1.24 g/cm3. This compound is monomeric with a pseudotrigonal coordination environment around the Sm atom. The crystals of II are rhombic: a 8.969(2); b 15.964(4); c 21.701(5) Å; space group Pc2/n; dcalcd 1.30 g/cm3. The lattice of II is built up of planar polymer grids between which crystallizational THF molecules are located.
