BIS（TETRAMETHYLCYCLOPENTADIENYL）RUTHENIUM（Ⅱ）——A FULLY ECLIPSED SANDWICH COMPOUND

摘要

＜正＞ A new compound, bis（tetraunethylcyclopentadienyl）ruthenium has been synthesized by reduction reaction of tetramethylcyclopentadiene, RuCl3 and Zn in situ. The results of X-ray diffraction studies demonstrate the compound to be of a fully eclipsed conformation. The crystal belongs to monoclinic system, space group C2/c with cell parameters a = 22.075（3）, b =10.674（3）,c=14.135（2） A,β= 101.74（1）°,V = 3261.1A3,Dc=1.4 gcm-3, Z = 8.Several cycles of block matrix least-squares refinement gave the final R = 0.034.
