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(tri­fluoro­meth­yl)phenyl-2κC1](hydrido-2κH)(iodido-1κI)bis­[1,1(η5)-penta­methyl­cyclo­penta­dien­yl]germaniumuranium(Ge—U), [GeU(C10H15)2(C8H3F6)2HI], and bis­[3,5-bis­(tri­fluoro­meth­yl)phenyl-2κC1](fluorido-1κI)(hydrido-2κH)bis­[1,1(η5)-penta­methyl­cyclo­penta­dien­yl]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) A].
