Structural modifications of M5O4I11 (M = Nb, Ta) cluster networks from heterogeneous solid-state reactions

Popis výsledku v původním jazyce

The cluster compounds M5O4I11 (M = Nb, Ta) and Ta5O4I11(TaI5) were obtained from heterogeneous solid-state reactions and structurally characterised by single-crystal X-ray diffraction. Their crystal structures are based on the novel [M5O4] cluster core with metal (M) atoms arranged following the motif of a square pyramid. Iodide ligands contribute to different connectivities in the structures, resulting in (van der Waals type) waved layer structures. Two structural modifications exist for Ta5O4I11, denoted as o-Ta5O4I11 and m-Ta5O4I11, and the compound Ta5O4I11(TaI5) encloses [TaI5] molecules within voids of the structure. The two-dimensional nature of the structures and the presence of metal-to-metal bonding motivated investigations of the electronic properties through optical band-gap measurements, electrical conductivity studies, electronic band structure calculations, and X-ray photoelectron spectroscopy.
