Abstract
AbstractThe cluster compounds [Nb6I8Py6] and [Nb6I8Py6]I ⋅ 9Py, both with octahedral Nb6 metal atom cores, were obtained from the reaction of [Nb6I11] with pyridine (Py). Both compounds are rare examples of iodide supported hexanuclear cluster compounds, which are obtained through solvent‐based chemical reactions. The Nb6 cluster core is surrounded by μ3‐bridging iodido and apical‐bonded pyridine ligands. [Nb6I8Py6] contains 22 cluster‐based electrons (CBE's), whereas [Nb6I8Py6]I ⋅ 9Py is the oxidized version with 21 CBE's. The oxidation happens just by lowering the temperature from room temperature to −20 °C of the same starting materials as used for [Nb6I8Py6]. The structures of the two cluster compounds were determined by single‐crystal X‐ray diffraction.
