2-(3-tert-Butylpyrazol- l-ylmethyl)pyridine (CH2(Py) (3-ButPz),Py=2-pyridyl and Pz =pyrazol- 1-yl) has been prepared by the reaction of 3-tert-butylpyrazole and 2-chloromethylpyridine-HCl under basic conditions.Reaction of CH2(Py)(3-ButPz) and its analogs,namely CH2(Py)(Pz) and CH2(Py)(3,5-Me2Pz),with M(CO)6 (M=Mo or W) has been investigated,which yields six bidentate chelating complexes CH2(Py)(3-ButPz)M(CO)4,CH2(Py)(Pz)M (CO)4 and CH2(Py)(3,5-Me2Pz)M(CO)4.Treatment of CH2(Py)(3,5-Me2Pz)M(CO)4 with SnCl4 gives beterobimetallic complexes CH2(Py)(3,5-Me2Pz)M(CO)3(Cl)SnCl3.These newly synthesized complexes have been characterized by IR and NMR spectroscopy,and the structures of CH2(Py)(3-ButPz)W(CO)4 and CH2(Py)(3,5-Me2Pz)W(CO)3(Cl)SnCl3have been further confirmed by X-ray crystal diffraction.The electrochemical behavior of CH2 (Py)(3-ButPz)M(CO)4,CH2(Py)(Pz)M(CO)4 and CH2(Py)(3,5-Me2Pz)M(CO)4 has been investigated by cyclic voltammetry.CCDC:820993,6; 820994,8.
