The new meta ‐ and para ‐xylyl‐based phosphadithiamacrocycles 6‐phenyl‐6‐phospha‐3,9‐dithiabicyclo[9,3,1]pentadeca‐1(15),12,14‐triene (L2) and 6‐phenyl‐6‐phospha‐3,9‐dithiabicyclo[9,2,2]pentadeca‐1(13),12,14‐triene (L3) have been synthesised and characterised. The reactivity of these ligands and the previously described ortho ‐xylyl macrocycle 6‐phenyl‐6‐phospha‐3,9‐dithiabicyclo[9,4,0]pentadeca‐1(11), 12,14‐triene (L1) with [PdCl 2 (cod)] and K 2 [PtCl 4 ] has been studied. [MCl 2 (L)] complexes have been obtained and characterised by NMR spectroscopy. X‐ray structural analyses have been carried out in the case of [PdCl 2 L2]·CH 3 CN ( 2·CH 3 CN ) and [PdCl 2 L3] ( 3 ). In both compounds the Pd II ion adopts a slightly distorted square‐planar coordination defined by one S ‐thioether, the P‐phosphane atoms of the ligand and two chlorine atoms, which are oriented in a mutual cis position, whereas the second S ‐thioether atom of the ligand remains uncoordinated. According to the spectroscopic data, the same coordination mode is found for the Pt II complexes. (© Wiley‐VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
