中文摘要	the reaction of lncl3.2licl with 1 equiv of mecpna in thf gives the complexes [(thf)2li(mu-cl)2]2[mecpln(thf)] (ln = nd (1), la (2)) in good yield. these precursors react further with 2 equiv of linph2 to produce the new complexes [li(dme)3][mecpln(nph2)3] (ln = la (3), pr (4), nd (5)). they have been characterized by elemental analyses and ir and nmr spectra, as well as by structural analyses of 1 and 3. the chloride 1 crystallizes in the monoclinic space group p2(1)/n (no. 14) with a = 12.130 (5) angstrom, b = 17.343 (5) angstrom, c = 17.016 (5) angstrom, beta = 108.54 (3)-degrees, v = 3393.87 angstrom3, z = 4, and d(c) = 1.45 g/cm3. least-squares refinement led to a final r value of 0.051 (i greater-than-or-equal-to 3-sigma(i(o))) for 2004 independent reflections. complex 3 crystallizes in the monoclinic space group p2(1)/c (no. 14) with a = 18.335 (6) angstrom, b = 16.576 (5) angstrom, c = 17.461 (6) angstrom, beta = 96.04 (3)-degrees, v = 5277.17 angstrom3, d(c) = 1.26 g/cm3, z = 4, and r = 0.057 (i greater-than-or-equal-to 2.5-sigma(i(o))) for 3378 reflections. the structure of 3 consists of discrete ion pairs [li(dme)3]+ and [mecpla(nph2)3]- with average la-n and la-c(ring) distances of 2.459 (8) and 2.84 (1) angstrom, respectively.
