  Syntheses, characterization and structures of chromium group carbonyl complexes containing a multifunctional Ph2P(o-C6H4)CHN(CH2)2(o-C6H4N) ligand

  摘要：

  Reactions of the phosphine-imine-pyridine-containing ligand Ph2P(o-C6H4)CH=N(CH2)(2)(o-C6H4N) (PNN) with M(CO)(3)(NCMe)(3) (M = Cr, Mo, W) produce the tridentate complexes fac-M(CO)(3)(eta(3)-PNN). On the other hand, treating W(CO)(4)(NCMe)(2) with PNN results in the bidentate complex W(CO)(4)(eta(2)-PNN), which converts to fac-W(CO)(3)(eta(3)-PNN) upon heating, but no facial --> meridional isomerism is evidenced. The new compounds have been characterized by elemental analysis and mass, IR, and NMR spectroscopy. The molecular structures of W(CO)(4)(eta(2)-PNN), fac-W(CO)(3)(eta(3)-PNN) and fac-Mo(CO)(3)(eta(3)-PNN) are determined by an X-ray diffraction study. (C) 2000 Elsevier Science S.A.
