Abstract
1-Butyl-3-methylimidazolium tetrakis-(bis(trifluoromethanesulfonyl)amide)yttrium(III), [bmim][Y(Tf2N)4], was obtained from the ionic liquid 1-butyl-3-methylimidazoliumbis(trifluoromethanesulfonyl)amide, [bmim][Tf2N] and yttrium(III)bis(trifluoromethanesulfonyl)amide, Y(Tf2N)3. The crystal structure [monoclinic, C2/c (no. 15), a = 2096.(1), b = 1451.5(1), c = 1608.55(9) pm, β = 109.669(6)°, V = 4608.1(5)·106 pm3, Z = 4, R1 for 3874 symmetry independent reflections with I0>2σ(I0): 0.0438] contains YIII coordinated by four Tf2N-ligands which all adopt a transoid-conformation with respect to their –CF3 groups. The oxygen coordination polyhedron around YIII can be best described as a trigonal dodecahedron.One 1-butyl-3-methylimidazolium cation compensates for the charge of the complex [Y(Tf2N)4]− anion.
