  ESR of diphenylantimony radical in a triphenylantimony single crystal

  摘要：

  Ultraviolet irradiation of a single crystal of triphenylantimony produces an antimony centered radical with an anisotropic 121Sb coupling having principal absolute values of 704, 352, and 352 MHz and a g tensor with the same principal axis as the hyperfine interaction and components of 1.998, 2.045, and 2.065. This radical has been assigned to the diphenyl antimony radical with approximately zero s and 0.7 p character. The linewidth of the spectra are consistent with unresolved hyperfine structure due to spin density delocalized on the phenyl rings.

  A radical formed by x-irradiation of a single crystal of triphenylantimony is identified as Ph2Ṡb. Its ESR spectral parameters (for 121Sb) g1=1.9804, g2=2.1044, g3=1.9959, Tx=1270 MHz, Ty=−752 MHz, Tz=−699 MHz corrected for nuclear spin–orbit interactions and decomposed into isotropic (−60.3 MHz) and anisotropic (1330.3, −691.7, −638.7 MHz) components, and the nuclear quadrupole coupling constants e2Qqx=−101 MHz, e2Qqy=−205 MHz, e2Qqz=306 MHz, have been interpreted in terms of the radicals’s electronic structure and indicate that, like the analogous Ph2Ṗ and Ph2Ȧs radicals, the unpaired electron is localized on the 5pπ valence orbital of the antimony atom and that the radical is strongly bent, ∠CSbC≃98°.
