The cation [(PPh3)2Pt(H)OH2]+ previously suggested as an intermediate in the synthesis of [(Ph3P)3Pt2(μ-H)(μ-PPh2)Ph]+ has been isolated as the tetrafluoroborate salt and characterised by X-ray crystallography. The structure shows a large unit cell with three independent cations and extensive hydrogen bonding between the water molecules and the tetrafluoroborate anions. The rearrangement of [(PPh3)2Pt(H)OH2]+ in aqueous THF provides a convenient high yield route to [(Ph3P)3Pt2(μ-H)(μ-PPh2)Ph]+.
Graphical abstractThe preparation of trans-[(PPh3)2Pt(H)OH2]BF4 and its rearrangement to [(Ph3P)3Pt2(μ-H)(μ-PPh2)Ph]+ is described. X-ray crystallography of trans-[(PPh3)2Pt(H)OH2]BF4 shows a large unit cell with three independent cations and one additional water molecule in the asymmetric unit. There is extensive hydrogen bonding between the water molecules and the tetrafluoroborate anions. The rearrangement of [(PPh3)2Pt(H)OH2]+ in aqueous THF provides a convenient high yield route to [(Ph3P)3Pt2(μ-H)(μ-PPh2)Ph]+.Figure optionsDownload full-size imageDownload as PowerPoint slide
