Synthesis and structure of bis[(2E)-3-(2-furyl)prop-2-enoato]triphenylantimony Ph3Sb[O2CCH=CH(C4H3O)]2

Resumo

Bis[(2E)-3-(2-furyl)prop-2-enoato]triphenylantimony Ph₃Sb[O₂CCH=CH(C₄H₃O)]₂ is obtained for the first time by the reaction of triphenylantimony, hydrogen peroxide, and 2-furylpropene acid. The X-ray diffraction data show that the central atom of antimony is coordinated in the shape of a distorted trigonal bipyramid. The base of the bipyramid is formed by carbon atoms of phenyl ligands, and the apical vertices are occupied by acid residues. The IR and NMR spectra agree with the composition and structure of the compound.
