A triplet stibinidene

Year: 2023
Type: article
Abstract: Pnictinidenes (R-E; E = P, As, Sb or Bi) are long-sought reactive species, which are isoelectronic to carbenes. They feature either a singlet or triplet ground state depending on the electronic property of the substituents. Although isolable singlet carbenes and fairly stable triplet carbenes are well-documented, triplet pnictinidenes isolable under standard laboratory conditions remain elusive. Herein we report the isolation, characterizations and reactivity studies of a free stibinidene supported by a hydrindacene ligand. X-ray crystallographic analysis shows that it contains a one-coordinate antimony atom featuring a Sb–C single bond. Magnetometric investigations, in conjunction with highly correlated wavefunction based ab initio calculations unequivocally demonstrate that the stibinidene features a triplet electronic ground state.
