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.
