| Abstract: | Reaction of dimethylsilylene-bridged pyrrolyl cyclopentadienyl potassium salt(H4C5-SiMe2-NC4H4)K(Cp'K,2) with SmI2(THF)2 yielded the THF solvated divalent samarium complex(Cp')2Sm(THF)2(3).The coordinated THF molecules can be easily removed to give THF free,polymeric(Cp'2Sm)n(4).The crystal structure of 3 has been determined by X-ray single-crystal analysis,in which both the pendent pyrrolyl rings reside toward the samarium center,indicating the pendent pyrrolyl rings have pronounced effects on the structur... |
