| 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.
