摘要：

Under mild conditions [ReX(CO)(3)(THF)(2)] reacts with pyrazolylmethylpyridines to form the complexes fac-[ReX(CO)(3)(BPz)] and fac-[ReX(CO)(3)(BMPz)] (X = CI, Br, or I; BPz = 2,6-bis(pyrazol-1-ylmethyl)pyridine; BMPz = 2,6-bis(3,5-dimethylpyrazol-1-ylmethyl)pyridine) that involve BPz and BMPz acting as non-fluxional bidentate chelate ligands. Under more severe reaction conditions fac-[ReX(CO)(3)(BPz)] is converted to fac-[Re(CO)(3)(BPz)]X (X = Cl, Pr, or I). Trimethylplatinum(IV)iodide reacts with BPz to form fac-[PtMe3(BPz)]I, The crystal structure of fac-[Rel(CO)(3)(BMPz)] confirms the bidentate chelate bonding of BMPz with a N-Re-N angle of 85.8 degrees.
