Crochet, Aurélien Brog, Jean-Pierre Fromm, Katharina M. 2016-01-06 Oxidative substitution reactions of chromium(II) chloride with lithium phenoxide in the presence of water give access to new polynuclear chromium(III) aryloxide complexes and coordination polymers. While a one-dimensional coordination polymer based on chromium(III), [Cr₂(μ₃-OPh)₂(μ-OPh)₆(μ-OH)(μ₃-Li)₄(μ₃-Cl)₂Li(THF)₆]_<i>n</i>, is first obtained by serendipity, the controlled addition of water to the initial Cr(II) complex as well as variation of the stoichiometry lead to three new discrete chromium(III) aggregates, namely, [Cr(OPh)₄(μ-OH)Li₂(THF)₃]₂, [Cr₃Li₃(OPh)₉(μ₃-OH)(μ₃-O)(THF)₆], and [Cr₄(μ-OPh)₈(μ₃-OH)₆(μ-OH)₂Cl₂Li₆(THF)6]·2THF. The use of deuterated species allowed confirmation of the oxidation based on the addition of water by detection of H₂, HD, and D₂. During these investigations, we have also identified a THF-adduct of chromium(II) chloride, [CrCl₂(THF)₂], used in the literature as a precursor in numerous syntheses, but with a hitherto unknown structure. application/pdf https://folia.unifr.ch/global/documents/304926 https://folia.unifr.ch/documents/304926/files/fro_mmm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1021/acs.cgd.5b01084 info:eu-repo/semantics/openAccess License undefined Crystal Growth & Design. - 2016, vol. 16, no. 1, p. 189–199 info:eu-repo/classification/udc/54 Mixed metal multinuclear Cr(III) cage compounds and coordination polymers based on unsubstituted phenolate: design, synthesis, mechanism, and properties http://purl.org/coar/resource_type/c_6501
