The ever‐rising interest of researchers in octahedral halide cluster complexes is explained by their intrinsic superb luminescent properties. Nevertheless, to date chemistry of tungsten clusters, especially of iodide ones, has been poorly developed, and there is only a small number of known compounds. Two new compounds obtained in this work, (Bu 4 N) 2 [{W 6 I 8 }(NCS) 6 ] ( 1 ) and (Bu 4 N) 2 [{W 6 I 8 }(N 3 ) 6 ] ( 2 ), expand the field of iodide tungsten clusters with inorganic ligands. The compounds are characterized by single crystal XRD, HR‐ESI‐MS and FTIR spectroscopy and elemental analysis. Both clusters demonstrate typical bright orange‐red emission sensitive to the concentration of oxygen in the environment. Using 1,5‐dihydroxynaphthalene as a trap for singlet oxygen, the observed rate constant of 1 O 2 generation is determined.
