In agreement with the experimental results, DFT calculations indicated that the flavonoid ligand is coordinated to one of the three Cr(III) centers in an O,O-bidentate mode through the 5-hydroxy\/4-keto groups. In a comparative study involving the uncoordinated primuletin and its corresponding complex, systematic reactions with the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) showed that antiradical activity increases upon complexation.<\/jats:p>","DOI":"10.3390\/molecules20046310","type":"journal-article","created":{"date-parts":[[2015,4,10]],"date-time":"2015-04-10T17:06:18Z","timestamp":1428685578000},"page":"6310-6318","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["A Trinuclear Oxo-Chromium(III) Complex Containing the Natural Flavonoid Primuletin: Synthesis, Characterization, and Antiradical Properties"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5282-4675","authenticated-orcid":false,"given":"Anamaria","family":"Alexiou","sequence":"first","affiliation":[{"name":"Escola de Engenharia, Universidade Presbiteriana Mackenzie, Rua da Consola\u00e7\u00e3o 930, S\u00e3o Paulo, SP CEP 01302-000, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla","family":"Decandio","sequence":"additional","affiliation":[{"name":"Escola de Engenharia, Universidade Presbiteriana Mackenzie, Rua da Consola\u00e7\u00e3o 930, S\u00e3o Paulo, SP CEP 01302-000, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabrina","family":"Almeida","sequence":"additional","affiliation":[{"name":"Escola de Engenharia, Universidade Presbiteriana Mackenzie, Rua da Consola\u00e7\u00e3o 930, S\u00e3o Paulo, SP CEP 01302-000, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1877-1762","authenticated-orcid":false,"given":"Marcelo","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Departamento de Bot\u00e2nica, Instituto de Bioci\u00eancias, Universidade de S\u00e3o Paulo, Rua do Mat\u00e3o, 277, S\u00e3o Paulo, SP CEP 05508-090, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulete","family":"Romoff","sequence":"additional","affiliation":[{"name":"Escola de Engenharia, Universidade Presbiteriana Mackenzie, Rua da Consola\u00e7\u00e3o 930, S\u00e3o Paulo, SP CEP 01302-000, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reginaldo","family":"Rocha","sequence":"additional","affiliation":[{"name":"Los Alamos National Laboratory, Los Alamos, NM 87545, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2015,4,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Andersen, \u00d8.M., and Markham, K.R.
