Depending on the reaction stoichiometry, both the \u201cate\u201d complex [Ph2B\u00ad(Me2PCH2)2Fe\u00ad(\u03bc-Cl)2Li\u00ad(THF)2] (2) and the homoleptic complex [Ph2B\u00ad(Me2PCH2)2]2Fe\u00ad(3) can be prepared from FeCl2(THF)1.5. Further reaction of 3 with FeCl2(THF)1.5 produces the chloride-bridged dimer [Ph2B\u00ad(Me2PCH2)2Fe\u00ad(\u03bc-Cl)2Fe\u00ad(CH2PMe2)2BPh2]\u00ad(4). Attempts to reduce or alkylate 4 provide 3 as the only isolable product, likely a consequence of the low steric hindrance of the bis\u00ad(ylide)\u00addiphenylborate ligand. On the other hand, reaction of 4 with the strong field ligand CNtBu provides the six-coordinate, diamagnetic complex [Ph2B\u00ad(Me2PCH2)2Fe\u00ad(CNtBu)4]\u00ad[Cl]\u00ad(5). Electronic structure calculations for the bis\u00ad(ylide)\u00addiphenylborate ligand and homoleptic complex 3 suggest that the C\u00ad(ylide) atoms are strong \u03c3-donors with little \u03c0-bonding character. These initial results suggest the potential for this bis\u00ad(ylide)\u00addiphenylborate ligand in coordination chemistry.<\/jats:p>","DOI":"10.1021\/acs.inorgchem.0c02575","type":"journal-article","created":{"date-parts":[[2020,11,19]],"date-time":"2020-11-19T16:56:00Z","timestamp":1605804960000},"page":"17303-17309","source":"Crossref","is-referenced-by-count":5,"title":["Iron(II) Complexes of an Anionic Bis(ylide)diphenylborate\nLigand"],"prefix":"10.1021","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7970-8535","authenticated-orcid":true,"given":"Yafei","family":"Gao","sequence":"first","affiliation":[{"name":"Indiana University , , 800 East Kirkwood Avenue , , ,","place":["Bloomington, Indiana, United States, 47405"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maren","family":"Pink","sequence":"additional","affiliation":[{"name":"Indiana University , , 800 East Kirkwood Avenue , , ,","place":["Bloomington, Indiana, United States, 47405"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3206-4725","authenticated-orcid":true,"given":"Jeremy M.","family":"Smith","sequence":"additional","affiliation":[{"name":"Indiana University , , 800 East Kirkwood Avenue , , ,","place":["Bloomington, Indiana, United States, 47405"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2020,11,19]]},"reference":[{"key":"2026081720273794900_cit1a","doi-asserted-by":"publisher","first-page":"3311","DOI":"10.1002\/cber.19791121004","article-title":"Monomere Bis\u00ad[dialkylphosphonium-bis\u00ad(methylid)\u00adl-Komplexe\ndes Nickels, Palladiums und Platins","volume":"112","author":"Schmidbaur","year":"1979","journal-title":"Chem.
