Synthesis and Crystal Structure of Lanthanide Schiff Base Complex 2-OC6H4CHN(2,6-i-Pr2C6H3)2ErCl(THF)

摘要

The lanthanide Schiff base complex [2-OC6H4CHN(2,6-I-Pr2C6H3)]2ErCl(THF) (C42H52ClErN2O3) has been prepared by the reaction of anhydrous LnCl3 with 2 equiv. Of the sodium salt of the bidentate Schiff base N-(2,6-diisopropylphenyl)salicylaldimine in THF. The crystal structure was determined by X-ray diffraction analysis. The crystal belongs to triclinic, space group P1 with a = 9.200(1), b = 13.637(2), c = 16.705(2) A, α = 74.493(7), β = 77.979(8), γ = 81.306(8)°, V = 1965.2(4) A3, Z = 2, Mr = 835.60, Dc = 1.412 g/cm3, F(000) = 854, T = 193 K, λ(MoKα) = 0.7107 A and ( = 22.38 cm-1. The final R = 0.052 and wR = 0.076 for 8386 observed reflections with I ≥ 2σ(I).
