Crystal structures of metallocene complexes with uranium-germanium bonds.

The first structural examples of complexes with uranium-germanium bonds are presented, namely, bis-[3,5-bis-(tri-fluoro-meth-yl)phenyl-2κC (1)](hydrido-2κH)(iodido-1κI)bis-[1,1(η(5))-penta-methyl-cyclo-penta-dien-yl]germaniumuranium(Ge-U), [GeU(C(10)H(15))(2)(C(8)H(3)F(6))(2)HI], and bis-[3,5-bis-(tri-fluoro-meth-yl)phenyl-2κC (1)](fluorido-1κI)(hydrido-2κH)bis-[1,1(η(5))-penta-methyl-cyclo-penta-dien-yl]germaniumuranium(Ge-U), [GeU(C(10)H(15))(2)(C(8)H(3)F(6))(2)FH]. The two complexes both have a long U-Ge bond [distances of 3.0428†(7) and 3.0524†(7)†à ].
