本文合成了以环戊烯配位的羰基钌簇合物Ru_3(CO)_9(C_5H_6),用IR,~1H NMR,~(13)C NMR和元素分析等方法对此簇合物进行了结构表征,配体环戊烯的双键被打开并且分别配位于金属钌原子所组成的平面上和下,X射线进一步肯定了以上结论,簇合物为单斜晶系,空间群为P2_1/a,α=1.6498(8),b=1.3221(5),c=1.7330(6)nm,β=91.54(3)°,V=3.779(3)nm~3,Z=8,μ=23.5cm~(-1),D_c=2.18g/cm~3,F(000)=2352,最终偏差因子R=0.0754,R_w=0.0710. In this paper, a series of Ru_3 (CO) _9 (C_5H_6) complexes were synthesized by cyclopentene. Their structures were characterized by IR, ~ 1H NMR, ~ 13 C NMR and elemental analysis Characterization, the ligand double bond of cyclopentene is opened and respectively located in the metal ruthenium atoms formed by the plane and under the X-ray further confirmed the above conclusion, the cluster is monoclinic, the space group P2_1 / a , α = 1.6498 (8), b = 1.3221 (5), c = 1.7330 (6) nm, β = 91.54 (3) °, V = 3.779 (-1), D_c = 2.18g / cm ~ 3, F (000) = 2352, final deviation factor R = 0.0754, R_w = 0.0710.
