Tentative structural interpretation based on these data: The elemental analysis results are consistent with an empirical formula approximating to Mo2O10(trz). The observation of a singlet in the1H\u2005NMR spectrum suggests that both trz protons are equivalent and therefore the trz ligand most likely adopts a bridging N1\/N2 coordination mode to two equivalent Mo centers. The simplest species compatible with this coordination mode would be a dinuclear complex. Peroxomolybdenum complexes containing the dinuclear moiety {Mo2O2(\u03bc-O2)2(O2)2} (Mo2O10) are well known and usually contain an additional ligand such as sulfate or phosphate that acts as a bipodal ligand to the two Mo atoms. Considering that this is also the preferred coordination mode of triazole the complex [Mo2O2(\u03bc-O2)2(O2)2(trz)] containing an N1 N2-bridging trz can be proposed as a plausible structure for3."},{"key":"e_1_2_7_42_1","doi-asserted-by":"crossref","first-page":"5207","DOI":"10.1039\/C5CY02052B","volume":"6","author":"Gomes A.
