Synthesis and coordination behavior of Cu(I) bis(phosphaethenyl)pyridine complexes.
نویسندگان
چکیده
Cu(I) complexes bearing BPEP as a PNP-pincer type phosphaalkene ligand undergo effective bonding interactions with SbF(6)(-) and PF(6)(-) as non-coordinating anions to give [Cu(SbF(6))(BPEP)] and [Cu(2)(BPEP)(2)(μ-PF(6))](+), respectively [BPEP = 2,6-bis(1-phenyl-2-phosphaethenyl)pyridine]. NMR and theoretical studies indicate a reduced anionic charge of the μ-PF(6) ligand, which is induced by the strong π-accepting ability of BPEP.

Schiff base complexes of transition metals are of particular interest to inorganic chemists because of their structural, spectral and chemical properties, which are often strongly dependant on the nature of the ligand structure. Large number of metal (II) complexes with Schiff-base ligands has been extensively studied for their interesting structural specialties, applications and properties. Th...

متن کاملVersatile coordination chemistry of a bis(methyliminophosphoranyl)pyridine ligand on copper centres.
The coordination of a bis(methyliminophosphoranyl)pyridine ligand (L) to copper centres was studied. The use of copper(I) bromide precursors gave access to [LCuBr] (2) in which only one iminophosphorane arm is coordinated to the metal, as observed by X-ray crystallography and MAS (31)P NMR. Its fluxional behaviour in solution was demonstrated by VT-(31)P NMR, and investigated by DFT calculation...
