| Abstract: | The P-O ligand 3-(di(2-methoxyphenyl)phosphanyl)propionic acid (HL) was synthesized by a microwave-assisted reaction of a secondary phosphane. The coordination of HL to PtII yielded the neutral mononuclear complex trans-[PtCl(κ2-P,O-L)(κ-P-HL)] (1), while the reaction of PdClMe(η4-COD) (COD = 1,4-cyclooctadiene) with HL in the presence of NEt3 gave the anionic PdII compound of the formula (HNEt3)[PdClMe(κ2-P,O-L)] (2). Upon crystallization of the latter compound the neutral chloride-bridged dimetallic compound cis-[Pd(μ-Cl)Me(HL)]2 (3) was obtained. HL, 1 and 3·CH2Cl2 have been characterized by single crystal X-ray structure analyses. |
