The nature of ‘Pt(Ph2PCH2CH2PPh2).’ A platinum(I)–platinum(I) dimer containing bridging cyclometallated 1,2-bis(diphenylphosphino)-ethane; X-ray crystal structure
Abstract
Single-crystal X-ray structural analysis of a complex of empirical formula [pt(dppe)](dppe = Ph2PCH2CH2PPh2) formed by heating [Pt(OH)Me(dppe)]in methanol shows that it should be formulated as [Pt-µ-{o-C6H4P(Ph)CH2PPh2}]2 and that it contains cyclometallated dppe ligands bridging a Pt1–Pt1 bond.
