Secondary Phosphine Chalcogenides. X. Reactions of Diphenylphosphane Oxide, Ph2P(O)H, with the Bis(2,4-pentandionato) Complexes of Nickel, Palladium, and Platinum, Bis(cycloocta-1,5-diene)nickel(0) and Nickel Tetracarbonyl. Crystal and Molecular Structure of [Ni(acae) {(Ph2PO)2H}] (acac- = 0,0′-C5H7O2-)Reaction of [{Ni(acac)2}3] and [Pd(acac)2] with Ph2P(O)H yields [M(acac){(Ph2PO)2H}] (M = Ni, Pd) whereas [Pt(acac)2] results [Pt{(Ph2PO)2H}2]. The Nickel(0) complexes [Ni(cod)2] and [Ni(CO)4] react with Ph2P(O)H to give [Ni(cod)(Ph2PO)2] and [{Ni(μ-OPPh2)2}n], respectively. The IR and NMR spectra as well as some reactions of these complexes are described.The crystal structure of [Ni(acac){(Ph2PO)2H}] has been investigated by X-ray methods and refined to an R value of 0,099 (Rw = 0,088). The coordination geometry around the Ni atom is square planar with a slight tetrahedral distortion. The existence of a strong hydrogen bond within the (Ph2PO)2H- ligand is proved by the O…O distance at 237 pm.
Notes:
[{Ni(acac)2}3] und [Pd(acac)2] reagieren mit Ph2P(O)H zu [M(acac){(Ph2PO)2H}] (M = Ni, Pd), während [Pt(acac)2] [Pt{(Ph2PO)2H}2] ergibt. Die Nickel(0)-Komplexe [Ni(cod)2] und [Ni(CO)4] setzen sich mit Ph2P(O)H zu [Ni(cod)(Ph2PO)2] bzw. [{Ni(μ-OPPh2)2}n] um.Die IR- und NMR-Spektren dieser Komplexe und einige ihrer Reaktionen werden beschrieben.Die Kristallstruktur von [Ni(acac){(Ph2PO)2H}] wurde röntgenographisch bestimmt und bis zu einem R-Wert von 0,099 (Rw = 0,088) verfeinert. Die quadratisch-planare Koordinationsgeometrie um das Ni-Atom weist eine geringfügige tetraedrische Verzerrung auf. Das Vorliegen einer starken Wasserstoffbrückenbindung im (Ph2PO)2H--Liganden wird durch den O…O-Abstand von 237 pm bewiesen.
