New bright-red luminescent nitrophenolate complexes (Bu4N)2[{Mo6I8}(OR)6] (R = C6H4-p-(NO2) (1), C6H3-2,4-(NO2)2 (2)) have been prepared from (Bu4N)2[{Mo6I8}I6] and AgOR, characterized by X-ray analysis, UV-Vis and IR spectroscopies and ESI-mass spectrometry. Both complexes are stable in solutions, and show multiple quasi-reversible reduction waves at highly negative potentials in CV studies. Complex 2 shows a quasi reversible oxidation at E1/2 = 1.41 V (vs. Ag/AgCl). Both 1 and 2 are intensely coloured with very high molar absorption coefficients in the near-ultraviolet region, 143 380 and 151 050 l mol-1 cm-1 for 1 and 2, respectively. Similar to other [{Mo6I8}L6]2- clusters 1 and 2 upon UV photoexcitation display relatively narrow red emission. © The Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2016.
