C6H4)]2BMe [L = Cp2 (12), rac-Et(Ind)2 (13)]. Besides characterizations by NMR and elemental analysis of the above new complexes, six of them (2, 4, 5, 8, 9, and 13) have also been structurally characterized by X-ray single-crystal diffraction studies. “Activated” metallocene complexes 12 and 13 are inactive for ethylene or propylene polymerization. Complex 1 exhibits low activity for ring-opening

structural elucidations of novel boron and aluminum complexes incorporating the tripodal triamido [N3]3- ligand framework that is hypothesized to promote the preorganized pyramidal geometry for high Lewis acidity are reported. Salt metathesis between the in situ-generated trianionic lithium complexes of the tripodal amido ligands with BCl3 leads to boranes HC[SiMe2N(4-MeC6H4)]3B (1) and MeSi[SiMe2N(4-MeC6H4)]3B
