The molecular structure of (116-C6Me6)Ta(DIPP)Et216,17 m/z = 628 (%r), 630 (8'Br)) in >95% yield (by 'H NMR). (3; Figure 2) reveals an interesting comparison to the This reaction is no doubt driven by the lattice energy of parent chloride. Both structures feature a coordinated MgC12,as the expected product (716-C6Me6)Ta(DIPP)EtC1 C6Me6ligand which shows (i) substantial folding18 (the (5) is present in
