摘要： Since S. Trofimenko introduced these isosteric and isoelectronic ligands with poly(1-pyrazolyl)borates[1],the poly (pyrazolyl)alkane ligands have attracted much attention. Their coordinating behaviour with transition and main group metals has been extensively investigated in recent years[2]. The coordinating behaviour of bis(3,5-dimethylpyrazol-1-yl)ethane is often different from other poly(pyrazolyl) alkanes[3]. The VIB metals carbonyl complexes bonded with poly (pyrazolyl)alkanes have novel structures and unusual reactivities[4,5,6],which encourages us to investigate M-Sn bimetallic complexes with poly(pyrazolyl)alkanes. In this paper, we report the synthesis, characterization and reactivities of poly (pyrazol-1-yl)alkane tetracarbonylmolybdenum (tungsten) with R'SnCl3(R'=Ph,Cl).
