  In this paper, we report the first examples of trispyrazolylmethane complexes of rare earths. Reaction of LnCl(3) with Tpm* (tris(3,5-dimethylpyrazolyl)methane) in THF or acetonitrile gives good yields of the [Ln(Tpm*)Cl(3)] (Ln = Y, Ce, Nd, Sm, Gd, Yb). Tpm* adducts of the lanthanide triflates [Ln(Tpm*)(OTf)(3)(THF)] (Ln = Y, Ho, Dy) may also be prepared. The X-ray crystal structures of [Y(Tpm*)Cl(3)], [Sm(Tpm*)Cl(3)(THF)], and [Ln(Tpm*)(OTf)(3)(THF)] (Ln = Y, Ho) are reported. The halide/triflate complexes may be used to prepare the aryloxide complexes [Ln(Tpm*)(OAr(Me2))(3)] (Ln = Y, Nd, Sm, Yb; Ar(Me2) = C(6)H(3)-2,6-(CH(3))(2)), which are fluxional in solution as a result of interactions between the Tpm* and the aryloxide groups. The structures of the Nd and Sm complexes have been determined. Finally, the reaction of [Nd(BH(4))(3)(THF)(3)] with Tpm* in THF results in the displacement of two THF molecules to give [Nd(Tpm*)(BH(4))(3)(THF)]. Infrared spectra are consistent with tridentate borohydride coordination. The X-ray structures of these compounds indicate that the Tpm* ligand is less strongly bound than its anionic trispyrazolylborate analogues.
