Synthesis of Quinoline-Based Pt-Sb Complexes with L- or Z-Type Interaction: Ligand-Controlled Redox via Anion Transfer.

ABSTRACT: A series of Pt-Sb complexes with two or three L-type quinoline side arms were prepared and studied. Two ligands, tri(8-quinolinyl)stibane (SbQ₃, Q = 8-quinolinyl, 1) and 8,8'-(phenylstibanediyl)diquinoline (SbQ₂Ph, 2), were used to synthesize the Pt^II-Sb^III complexes (SbQ₃)PtCl₂ (3) and (SbQ₂Ph)PtCl₂ (4). Chloride abstraction with AgOAc provided the bis-acetate complexes (SbQ₃)Pt(OAc)₂ (5) and (SbQ₂Ph)Pt(OAc)₂ (6). To better understand the electronic effects of the Sb moiety, analogous bis-chloride complexes were oxidized to an overall formal oxidation state of +7 (i.e., Pt + Sb formal oxidation states = 7) using dichl
