(Chemical Equation Presented) Long sought structural data on an f-element tuck-in complex have been obtained for the title compound 1 that contains the first example of both tuck-in and tuck-over bonding in a ligand derived from C5Me5- by metalation (see scheme).

Several new synthetic routes to the sterically crowded (C5Me5)3U complex have been developed. (C5Me5)3U can be prepared by (a) reaction of [(C5Me5)2UH2]2 with tetramethylfulvene, (b) reduction of (C5Me5)2Pb with (C5Me5)2UH(DMPE), (c) reaction of [(C5Me5)2U(L)]+ (L = THF, DMPE) with K(18-crown-6)(C5Me5), and (d) reaction of [(C5Me5)2U] [BPh4] with KC5Me3. Reaction of (C5Me5)2UH(DMPE) with C8H8 forms the product of the (C5Me5)3U/ C8H8 reaction, [(C8H8)(C5Me5)U]2(C8 H8). The X-ray crystal structures of the (C5Me5)2U[N(SiMe3)2] and [(C5Me5)2U] [BPh4] precursors used in this study are reported, as well as the convenient synthesis of a new trivalent uranium precursor, (C5Me5)2UMe2K.
