Coordination chemistry of the metalloligand [Pt₂(μ-S)₂(PPh₃)₄] with nickel(II) complexes – an electrospray mass spectrometry directed synthetic study. Inorganica Chimica Acta, 357(4), 1152-1160.https://hdl.handle.net/10289/3409The 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(PPh₃)₂] gives [Pt₂(μ-S)₂(PPh₃)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. Reactions of [Pt₂(μ-S)₂(PPh₃)₄] with a range of nickel(II) substrates have been explored using electrospray mass spectrometry, coupled with synthesis and characterization in selected systems. The X-ray crystal structure of [Pt₂(μ-S)₂(PPh₃)₄Ni(NCS)(PPh₃)]⁺PF₆⁻is reported.application/pdfenThis is an author’s accepted version of an article published in the journal: Inorganica Chimica Acta.
