摘要：
Treatment of dichloromethane solutions containing 18-crown-6, KX, and PPh3), in a 1:1:1 ratio, with pentane leads to quantitative precipitation of the complexes [(18-crown-6)K(OPPh3)X] (X: 1, 1; Br, 2; NCS, 3). Complexes 1-3 are stable in the solid state but dissociate readily in solution. The structure of 1 is established by a single-crystal X-ray diffraction study. Crystallographic data for 1: space group R3m, a = 14.432 (6) angstrom, c = 13.690 (2) angstrom, V = 2469.5 (11) angstrom3, Z = 3, R = 0.028, R(w) = 0.019.
