Abstract

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(η⁵)-penta-methyl-cyclo-penta-dien-yl]germaniumuranium(Ge-U), [GeU(C₁₀H₁₅)₂(C₈H₃F₆)₂HI], and bis-[3,5-bis-(tri-fluoro-meth-yl)phenyl-2κC ¹](fluorido-1κI)(hydrido-2κH)bis-[1,1(η⁵)-penta-methyl-cyclo-penta-dien-yl]germaniumuranium(Ge-U), [GeU(C₁₀H₁₅)₂(C₈H₃F₆)₂FH]. The two complexes both have a long U-Ge bond [distances of 3.0428 (7) and 3.0524 (7) Å].
