Abstract

The spontaneous formation of the heteroligated complex [PtCl(κ ²-Ph₂PCH₂CH₂SMe)(Ph ₂PCH₂CH₂SPh)]-Cl (8a) by a novel ligand rearrangement process has been observed. By using the weak-link approach, the relative arrangement of the alkyl and aryl groups can be controlled by abstraction of chloride from 8a to form the closed complex [Pt(κ ²-Ph₂PCH₂CH₂SMe) (κ²-Ph₂PCH₂CH₂SPh)] [BF ₄]₂ (5) and reopening using halide ions to form semiopen complexes [PtX(κ²-Ph₂PCH₂CH ₂SMe)(Ph₂PCH₂CH₂SPh)]-BF ₄ (8b; X = Cl^-) and (8c; X = I^-). Analogous procedures using Ph₂PCH₂CH₂SMe and 1,4-(Ph ₂PCH₂CH₂S)₂C₆H ₄ lead to heteroligated bimetallic complexes 7 and 9, illustrating that this ligand rearrangement process can be used as a tool for the assembly of complementary metallosupramolecular structures.
