Abstract

Reaction of Zr((OPr)-Pr-i)(4) or Sn[N(SiMe3)(2)](2) with the tris-phenol amine ligand H3L(Me/Me) results in the formation of zirconium or tin complexes containing the new C-3-symmetric zwitterionic ammonium- trisphenolate ligand HL2-, while increasing the steric bulk of the ligand results in the isolation of a zirconium complex containing the known trianionic ligand L3-.
