N2 - IR and Raman spectroscopies are important characterisation methods for Nb and Ta octahedral halide clusters [M6Xi12Xa6]x (M = Nb, Ta; X = Cl, Br; x = 4–, 3–, 2–; i – “inner”, bridging ligand belonging to the cluster core, a – “ausser” or “apical” terminal ligand) and the polymeric Ta6I14. The structural and spectroscopic data of these compounds (x = 4–) and their corresponding {M6X12}2+ core clusters were systematically investigated and analysed by means of quantum chemical calculations.
