摘要：
Lithium(I) and uranium(VI) amido-tethered Bu-t-substituted N-heterocyclic carbene (NHC) complexes exhibit very distorted metal - carbene bonds; the corresponding magnesium(II) and mesityl-substituted NHC uranium(VI) complexes are undistorted; the distortion does not affect the ligand binding strength, suggesting a dominance of electrostatic character in closed-shell electropositive metal - carbene bonds.
