The complex crystallizes in the monoclinic space group C2/c (#15) with lattice parameters a=16.0771(5) Å, b=13.1196(4) Å, c=16.9391(6) Å, β=116.853(1)°, V=3187.61(18) Å3, Z=4, D calc=1.532gcm-3. The six-coordinate uranium(VI) center adopts an all-trans octahedral geometry consisting of mutually trans oxo groups, silylamido ligands, and neutral THF donors. Structural comparisons of this uranyl(VI) bis(amido) complex with a related tris(amido) derivative within the series are made based on symmetry, charge, and coordination number. Graphical Abstract: The X-ray crystal structure of the title complex is reported, providing comparisons based on symmetry, charge, and coordination number with a related uranyl(VI) amido derivative within this series.
