σ-Organoniobium Compounds with [NbR₄]⁻ and NbR₄ Stoichiometries

Securely nested: The first examples of σ‐organoniobium compounds with [NbIIIR4]− and NbIVR4 stoichiometries are reported. The Nb centers within the [Nb(C6Cl5)4]q− units (q=0, 1) are located in triakis tetrahedral environments formed by the combination of inner NbC4 (see picture; gray) and outer NbCl...

Summary:Securely nested: The first examples of σ‐organoniobium compounds with [NbIIIR4]− and NbIVR4 stoichiometries are reported. The Nb centers within the [Nb(C6Cl5)4]q− units (q=0, 1) are located in triakis tetrahedral environments formed by the combination of inner NbC4 (see picture; gray) and outer NbCl4 (green) tetrahedra.
