Oktober 1994 Cymantrene Thioether, Palladium(II) Complexes, Platinum(II) Complexes Treatment of the cymantrene thioether [C5(SM e)5]M n(CO)3 (lib) with Na2PdCl4 or K2PtCl4 yields the bimetallic chelate complexes [C5(SM e)5]M n(CO)3*MCl2 (M = Pd (2) or Pt (3)). Similarly, the S,P-chelate complexes [C5Cl2(SR )2(PPh2)]M n(CO)3*PdCl2 (R = Me (4a), Ph (4b)) can be obtained from the corresponding mononuclear cymantrene derivatives and Na2PdCl4 or (PhCN)2PdCl2. Analysis of the 'H NMR spectra only allows for the Pt complex the identification of one meso form, which seems to be favoured by 2:1, together with the D,L forms.
