	abstract = {Reactions of metal-metal bonded homobimetallic (Pd-2) and heterobimetallic (PtPd) complexes, supported by a P,P{\textquoteright}-bridging-bis(P,N-chelating) coordination mode of the potentially hexadentate ligand 1,1-bis[di(o-N,N-dimethylanilinyl)phosphino]methane (dmapm), with CO, diethylacetylenedicarboxylate (DEAD), and thiols (FISH) in CH2Cl2 are described. At room temperature, rac-Pd2Cl2(mu-N,P:P{\textquoteright},N{\textquoteright}-dmapm) gives the stable complexes Pd2Cl2(mu-CO)(2)-(mu-P:P{\textquoteright}-dmapm) and PdCl(eta(2)-DEAD)(mu-P:P{\textquoteright}, N-dmapm)PdCl (which is fluxional in solution), while rac-PtPdCl2(mu-N,P:P{\textquoteright}, N{\textquoteright}-dmapm) disproportionates to PtCl2(P,P{\textquoteright}-dmapm) and Pd metal, although at low temperature intermediate carbonyl species are detected in the CO reaction. The reactions with thiols in the presence of triflic acid (HOTf) generate rac-[MPdCl2(mu-SR)(mu-N,P:P{\textquoteright},N{\textquoteright}-dmapm)][OTf] and H-2 for both M = Pt and Pd. In CH2Cl2, PdX2(dmapm) species (X = halide or CN) exist as equilibrium mixtures of P,P{\textquoteright} and P,N-ligated forms. For X = Cl, the P,P{\textquoteright}-PN equilibrium is governed by DeltaHdegrees = -5.5 +/- 0.5 kJ mol(-1) and DeltaSdegrees = 10 +/- 1 J mol(-1) K-1, and the ring-strain energy within the P,P{\textquoteright}-isomer is similar to32 kJ mol(-1); the equilibrium increasingly favors the P,N-form with X = CN much greater than I > Br > Cl. The solid-state structures of rac-[PtPdCl2(mu-SEt)(mu-NP:P{\textquoteright},N{\textquoteright}-dmapm)][OTf] and PdCl2(P,N-dmapm) are presented; the latter contains both bound and free N- and P-atoms of identical types in the same molecule and permits an assessment of sigma- and pi-bonding between these atoms and Pd.},

The reactions of 1 and 2 with olefins (ethylene, maleic anhydride, diethyl maleate, and olefinic nitriles) are studied and some square-planar Pt(PR3)2(eta-2-olefin) species isolated (PR3 = the pyridylphosphine). No olefin hydration products are observed on heating the olefin complexes in aqueous solution. Oxidative addition of MeI to 1 and to 2 gives the trans-PtI(Me)(PR3)2 species. However, the trans-Pt(H)Cl(PR3)2 species is isolated only from reaction of 2 with gaseous HCl; the hydride reacts with acrylonitrile to form cis-PtCl(CH2CH2CN)(PR3)2.},
