Reaction of the carbonyl complexes with the oxidant tert-butyl hydroperoxide (TBHP) (either separately or in situ) gives oxomolybdenum(VI) hybrid materials that are proposed to possess one-dimensional polymeric structures in which adjacent oxo-bridged dioxomolybdenum(VI) moieties are further linked by bidentate bridging triazole (trz) ligands. A pronounced ligand influence on catalytic performance was found and the best result (quantitative epoxide yield within 1 h at 70 \u00b0C) was obtained with the 1,2,3-triazole oxomolybdenum(VI) hybrid. Both molybdenum oxide-triazole compounds displayed superior catalytic performance in comparison with the known hybrid materials [MoO3(trz)0.5], which have different structures based on organic-inorganic perovskite-like layers. With aqueous H2O2 as the oxidant instead of TBHP, all compounds were completely soluble and active. A pronounced ligand influence on catalytic performance was only found for the hybrids [MoO3(trz)0.5], and only the 1,2,4-trz compound displayed reaction-induced self-precipitation behavior. An insight into the type of solution species that may be involved in the catalytic processes with these compounds was obtained by separately treating [MoO3(1,2,4-trz)0.5] with excess H2O2, which led to the crystallization of the complex (NH4)1.8(H3O)0.2[Mo2O2(\u03bc2-O)(O2)4(1,2,4-trz)]\u00b7H2O. The single-crystal X-ray investigation of this complex reveals an oxo-bridged dinuclear structure with oxodiperoxo groups being further linked by a single triazole bridge.<\/jats:p>","DOI":"10.3390\/molecules24010105","type":"journal-article","created":{"date-parts":[[2018,12,28]],"date-time":"2018-12-28T11:52:42Z","timestamp":1545997962000},"page":"105","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A Comparative Study of Molybdenum Carbonyl and Oxomolybdenum Derivatives Bearing 1,2,3-Triazole or 1,2,4-Triazole in Catalytic Olefin Epoxidation"],"prefix":"10.3390","volume":"24","author":[{"given":"Lucie S.","family":"Nogueira","sequence":"first","affiliation":[{"name":"Department of Chemistry, CICECO\u2014Aveiro Institute of Materials, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]},{"given":"Patr\u00edcia","family":"Neves","sequence":"additional","affiliation":[{"name":"Department of Chemistry, CICECO\u2014Aveiro Institute of Materials, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]},{"given":"Ana C.","family":"Gomes","sequence":"additional","affiliation":[{"name":"Department of Chemistry, CICECO\u2014Aveiro Institute of Materials, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]},{"given":"Tatiana A.","family":"Amarante","sequence":"additional","affiliation":[{"name":"Department of Chemistry, CICECO\u2014Aveiro Institute of Materials, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2051-5645","authenticated-orcid":false,"given":"Filipe A.
