Abstrakt:	Novel unsymmetrical SCS′-pincer ligands, 1-[PhNHC(S)]-3-[Ph2P(S)NH]-C6H4(3) and 1-[PhNHC(S)]-3-[Ph2P(S)O]C6H4(7), bearing a thiocarbamoyl moiety in combination with thiophosphorylamino- and thiophosphoryloxy-donating groups, respectively, were obtained viathiophosphorylation of 3-amino- and 3-hydroxy-benzoic acid (thio)anilides 1and 6. Direct cyclometallation of the central benzene ring in the ligands 3and 7in reaction with (PhCN)2MCl2(M = Pd, Pt) as a metal precursor afforded κ3-SCS′-hybrid pincer complexes 8, 9with 5- and 6-membered fused metallacycles in good to high yields (67–95%). The complexes 8and 9were characterized by multinuclear NMR (31P, 1H, 13C) and IR spectroscopy as well as single-crystal X-ray crystallography. Palladium complexes 8aand 9awere shown to be active catalysts for the Suzuki–Miyaura cross-coupling reaction. In the solid state the ligands 3and 7as well as their Pt(ii) and Pd(ii) complexes 8and 9are luminescent at 300 K. The emission of the complexes has the different origin depending on the metal nature.
