  Syntheses and coordination studies of 2-(diphenylphosphinomethyl)pyridine N,P dioxide with Co2+, Ni2+, Cu2+ and Zn2+ tetrafluoroborate

  摘要：

  Several new coordination complexes of Co2+, Ni2+, Cu2+ and Zn2+ were synthesized by the reaction of their corresponding tetrafluoroborate salts with 2-(diphenylphosphinomethyl)pyridine N,P dioxide, L. All structures were determined by single-crystal X-ray crystallography showing an octahedral environment around the metal centers. Single crystals of M(BF4)(2)L-2(S)(2) (M = Co2+, Ni2+ or Zn2+; S = MeOH or CH3CN) were obtained at -5 degrees C by slow diffusion of ether into solutions of these complexes. When these crystals were re-dissolved in methanol and allowed to grow again at room temperature using the same technique and solvent system, the product obtained presented a 3:1 ratio ligand-to-metal. The complex [Cu(BF4)(2)L-2(MeOH)(BF4), exhibits two units of L, one molecule of MeOH and one counter-anion coordinated to the Cu2+ center. This can be attributed to the steric restrictions generated by the lower symmetry in this complex, a product of significant Jahn-Teller effects, which favors a long range interaction between the metal center and a less coordinative counter-anion, compared to a MeOH unit. A 1:1 ligand-to-metal ratio complex of Ni2+ was also obtained by allowing the starting materials to react for only a short time. Attempts to obtain single crystal of complexes of Co2+, Cu2+ or Zn2+ in a 1:1 ratio were not successful. The resulting 3:1 ligand-to-metal products were fully characterized by elemental analysis, UV-Vis spectroscopy and FT-IR spectroscopy. 2013 Elsevier B.V. All rights reserved.

  Phosphorylmethylpyridines and their N-oxides: Synthesis and equilibrium CH-acidity

  摘要：

  Certain phosphorylmethylpyridines and their N-oxides were synthesized, which are of interest as extractants and complex-forming agents. Their equilibrium CH-acidity with reference to 9-phenylfluorene (K+ counterion) was studied by the indicator method in dimethyl sulfoxide. The acidifying action of a series of pyridine groupings was characterized by means of sigma-C- values.

  The coordination properties of the 2-[(diphenylphosphanyl)methyl]pyridine N,P-dioxide ligand towards three different silver(I) salts are described. The molecular structures of the coordination complexes obtained showed a strong dependence on the 2-[(diphenylphosphanyl)methyl]pyridine N,P-dioxide ligand and the binding ability of the counterion. The strongly binding trifluoroacetate ion yielded a unique
