Complexes of triphenylphosphine oxide with lanthanide bromides
The reaction between hydrated lanthanide bromides and triphenylphosphine oxide in 1:3 and 1:4 ratios in ethanol gave a series of complexes [LnBr2(Ph3PO)4]Br (Ln = Pr, Nd, Gd, Tb, Er, Yb, Lu) which contain ethanol and water in the lattice, regardless of the ratio of reactants used. The single crystal x-ray structures of [NdBr2(Ph3PO)4]Br, [GdBr2(Ph3PO)4]Br and [YbBr2(Ph3PO)4]Br have been determi...
متن کاملIsocyanide and Phosphine Oxide Coordination in Binuclear Chromium Pacman Complexes
The new binuclear chromium Pacman complex [Cr2(L)] of the Schiff base pyrrole macrocycle H4L has been synthesized and structurally characterized. Addition of isocyanide, C≡NR (R = xylyl, tBu), or triphenylphosphine oxide donors to [Cr2(L)] gives contrasting chemistry with the formation of the new coordination compounds [Cr2(μ-CNR)(L)], in which the isocyanides bridge the two Cr(II) centers, and...
متن کاملPhosphine and diphosphine complexes of tungsten(VI) oxide tetrafluoride
The reaction of [WOF4(MeCN)] with the diphosphines, Me2PCH2CH2PMe2 or o-C6H4(PMe2)2, in anhydrous Et2O produced high yields of [WOF4(diphosphine)], the X-ray crystal structures of which reveal seven-coordinate pentagonal bipyramidal molecules with axial O/F. In contrast, the reaction of [WOF4(MeCN)] and PMe3 forms the six-coordinate [WOF4(PMe3)]. These unusual W(VI) complexes have been characte...
متن کاملPhosphine oxide functionalised imidazolium ionic liquids as tuneable ligands for lanthanide complexation.
A series of novel, phosphine oxide functionalised ionic liquids have been synthesised and their application as tuneable lanthanide complexing agents is demonstrated.
متن کاملSynthesis. solid state structure and spectro-electrochemistry of ferrocene-ethynyl phosphine and phosphine oxide transition metal complexes
The synthesis of ferroeene-ethynyl phosphine platinum dichloride complexes based on (FeC=C)"Ph3 _ nP (ta, 11 = 1; tb, 11 = 2; te, 11 = 3; Fe = ferroeenyl, (.,s-CsHs)(.,s-CsH4 )Fe) is deseribed. Air-oxidation of te afforded (FeC= ChP=O (6). Treatment of ta-tc with [(PhC= NJ,PtClz] (2) or [(tht)AuCI] (tht = tetrahydrothiophene) (7), respeetively, gave the heterometallie transition complexes cis-[...
