Abstract

Treatment of anhydrous CuCl2 with excess NMe3 at room temperature gives the yellow mono-adduct CuCl2.1.1NMe3 (I). Attempted recrystallization of I from CH2Cl2 provides the orange tetrachlorocuprate(II) salt [Me3NCH2Cl]2[CuCl4] (II). The same product is obtained from direct treatment of CuCl2 with a mixture of NMe3/CH2Cl2. The structure of II has been determined by conventional X-ray diffraction techniques: crystals are monoclinic, space group P2(1)/n with cell constants a = 17.20(1), b = 11.78(1), c = 9.067(7) angstrom, beta = 90.5(1)-degrees, U = 1837.0 angstrom 3, Z = 4. The final R value for 1620 unique reflections (I > 2-sigma(I)) is 0.062 (R(w) = 0.064). The structure consists of two independent [Me3NCH2Cl]+ cations and one discrete [CuCl4]2- anion whose geometry is intermediate between tetrahedral and square planar with trans Cl-Cu-Cl angles of 132.5(1) and 134.4(1)-degrees and Cu-Cl distances in the range 2.232(3)-2.253(3) angstrom.
