The synthesis, characterization, and luminescence properties of (Bu 4 N) 2 [Mo 6 I 8 (NCS) 6 ] are reported. Orange crystals of (Bu 4 N) 2 [Mo 6 I 8 (NCS) 6 ] were crystallized from acetone solution and used for X‐ray single‐crystal structure determination and refinement, yielding a structure with a centrosymmetric [Mo 6 I 8 (NCS) 6 ] 2– ion. Photoluminescence studies on the crystalline solid revealed a broad excitation in the UV/Vis region and an emission around 690 nm. The red emission intensity decreases with increasing partial pressure of atmospheric molecular O 2 .
