Synthesis, characterization and reactivity of a neutral antimony(III) complex

Pincer complexes are widely used in organometallic and coordination chemistry. The role of antimony as a central donor atom in pincer ligands has been extensively explored in recent years. Although phenylenediamine derived PXP (X= B, Al, C, Si, Ge, Sn, N) type ligands exhibit diverse reactivity, analogues species based on antimony have been reported less frequently. Herein, we report a new PSbP complex and evaluate its reactivity. These species will broaden the family of phenylenediamine derived pincer complexes.

Automated summary

Pincer complexes, with antimony as a central donor atom, have been explored in recent years. While phenylenediamine derived PXP ligands show diverse reactivity, analogues based on antimony are less commonly reported. The new PSbP complex reported in this study will expand the family of phenylenediamine derived pincer complexes.
