The reactivity of [Pt2(μ-S)2(PPh3) 4] towards a range of nickel(II) complexes has been probed using electrospray ionisation mass spectrometry coupled with synthesis and characterisation in selected systems. Reaction of [Pt2(μ-S) 2(PPh3)4] with [Ni(NCS)2(PPh 3)2] gives [Pt2(μ-S)2(PPh 3)4Ni(NCS)(PPh3)]+, isolated as its BPh4- salt; the same product is obtained in the reaction of [Pt2(μ-S)2(PPh3)4] with [NiBr2(PPh3)2] and KNCS. An X-ray structure determination reveals the expected sulfide-bridged structure, with an N-bonded thiocyanate ligand and a square-planar coordination geometry about nickel. A range of nickel(II) complexes NiL2, containing β-diketonate, 8-hydroxyquinolinate, or salicylaldehyde oximate ligands react similarly, giving [Pt2(μ-S)2(PPh3)4NiL] + cations.

The reactivity of cis-[PtCl2(CO)(PPh3)] toward SnCl2·2H2O has been studied with use of acetone, acetonitrile, and chloroform as solvents. In acetone and acetonitrile, ligand rearrangement reactions occur, but in chloroform only the simple insertion of SnCl2 into one Pt-Cl bond is observed. Similar solvent effects are observed in the reactions of [Pt2(μ-Cl)2Cl2(PR3)2] with SnCl2·2H2O, which yield the trans-[PtCl(SnCl3)2(PR3)]- anions in acetone solution but the simple insertion products, [Pt2(μ-Cl)2(SnCl3)2(PR 3)2], in chloroform solution. Reactions of the related complexes cis-[PtCl2(L)(PPh3)] (L = SMe2, C5H5N, p-MeC6H4NH2) with SnCl2·2H2O in acetone solution also occur via ligand rearrangements. 1H, 31P{1H}, and 119Sn{1H} NMR methods, utilizing 13C-labeled carbon monoxide as a probe of geometry, have been employed to assign solution structures and to monitor reaction pathways.
