Treatment of MOF-5 with NbCl 4 (THF) 2 in acetonitrile leads to incorporation of Nb(iv) centers in a fashion that diverges from the established cation metathesis reactivity of this iconic material. A combination of X-ray absorption spectroscopy analysis and reactivity studies altogether supported by density functional theory computational studies document an unprecedented binding mode for the Zn 4 O(O 2 C-) 6 secondary building units (SBUs), which in Nb(iv)-MOF-5 function as κ  2 -chelating ligands for NbCl 4 moieties, with no exchange of Zn 2+ observed. This unusual reactivity expands the portfolio of post-synthetic modification techniques available for MOFs, exemplified here by MOF-5, and underscores the diverse coordination environments offered by this and potentially other MOFs towards heterometal species.

Quo vadis niobium? Divergent coordination behavior of early-transition metals towards MOF-5
