Cis-(Ph3P)2PtCl2 and cis-(Ph3P)2PtCO3 were prepared mechanochemically from solid reactants in the absence of a solvent; cis-(Ph3P)2PtCl2 was obtained in 98% yield after ball-milling of polycrystalline PtCl2 and Ph3P; the mechanically induced solid-state reaction of cis-(Ph3P)2PtCl2 with an excess of anhydrous K2CO3 produced cis-(Ph3P)2PtCO3 in 70% yield; the formation of transition metal complexes as a result of mechanochemical solvent-free reactions has been confirmed by means of solid-state 31P MAS NMR spectroscopy, X-ray powder diffraction and differential thermal analysis.

describe the synthesis, structure and reactivity of novel bis(1-alkenyl)platinum(II) complexes, Pt[CH2(CH2)nCH CH2]2L2 (where L2 = dppp, dppe, dppm and n = 1, 2). The stability of the title complexes with the different ligands is discussed. The steric, chelating and electronic properties of the ligands have a significant impact on the structure as well as on the reactivity of the complexes. Novel reactions

The reaction of CH2Cl2 with (Ph3P)2PtO2 affords cis-(Ph3P)2PtCl2, (Ph3P)2Pt(CO3), Ph3PO and H2O. 31P1H NMR studies of this oxidation of CH2Cl2 to a carbonato ligand give evidence for the intermediates (Ph3P)2Pt(OOCH2Cl)Cl and (Ph3P)2 PtOOCH2OO. With formic acid (Ph3P)2PtO2 yields the formate complex cis-[(Ph3P)2Pt(OOCH)2].

The reaction chemistry and X-ray crystal structure of the platinum(II) oxo complex [PtL2(µ-O)]2·LiBF4(L = PPh3) reveal the presence of a highly basic oxo ligand and an unusual oxo–LiBF4 interaction.
Synthesis, characterization and antiproliferative activity of three platinum(II) complexes of l-carnitine. The first structural determination of a platinum complex containing carnitine
provided of specific transporters through the blood–brain barrier (BBB), has been coordinated for the first time to Pt(II) giving [Pt(PPh3)2( l -carnitine-O,O′)]BF4 (1), cis-[Pt(PPh3)2( l -carnitine-O)2](BF4)2 (2) and cis-[Pt(PPh3)2( l -carnitine-O)Cl]BF4 (3). The X-ray crystal structure of complex 1 is the first reported for a Pt carnitine complex. The antiproliferative activity of 1, 2 and 3, in comparison
