Abstract

The reactions of the Sn·Sn one-electron bonded compound [K(THF)₆][LSn·SnL] (L = N,N-dpp-o-phenylenediamide) (1) with 1,2-diketones afforded three mononuclear complexes with the doubly reduced diolates, [K(DME)]₂[LSn(BZ^2–)₂] (2) (BZ = benzil), [K₂(THF)₃][LSn(PQ^2–)₂] (3) (PQ = 9,10-phenanthrenequinone), and [K₂(THF)₂(Et₂O)][LSn(AcQ^2–)₂] (4) (AcQ = acenaphthenequinone). These complexes feature a formal Sn(IV) center that is six-coordinated by three chelating ligands (L and two diolates). In comparison, the reaction of 1 with 9,10-anthraquinone (AnQ) yielded the dinuclear complex [K(DME)₄]₂[LSn(AnQ^2–)SnL] (5) with two Sn(II) centers, which are three-coordinated by a ligand L and a bridging AnQ^2– dianion. The products were characterized by single-crystal structures, ¹H, ¹³C, and ¹¹⁹Sn NMR spectroscopy, and DFT calculations.
