Three substituted tris(pyrrolyl-α-methyl)amines (H 3[Aryl3TPA]) (Aryl = 2,4,6-C6H 2Me3, 2,4,6-C6H2(i-Pr)3 (Trip), or 3,5-C6H3(CF3)2) have been prepared. An X-ray study of [Trip3TPA]MoCl shows it to be a distorted trigonal bipyramidal species in which the 2,4,6-triisopropylphenyl substituents surround and protect the apical chloride. Attempts to prepare other Mo, Zr, and Hf complexes yielded species in which one pyrrole-containing arm remained free (Mo) or dimethylamine remained in the coordination sphere of [Aryl3TPA]3- complexes (Zr, Hf).
