本文合成了庚烯配位的羰基钌氢簇合物H~3Ru~3(CO)~9(C~7H~1~1),用IR, NMR,MS和元素分析等手段对此簇合物进行了结构表征,推测其为含有金属- 氢键的羰基钌簇合物,并且庚烯的双键被打开.X射线衍射测定进一步肯定了上述结论.簇合物为三斜晶系,空间群为PI.晶胞参数:a=0.9726(2)nm,b=0.9868(1)nm,c=1.1104(2)nm,α=103.22(1)°,β=89.89(1)°,γ=91.55(1)°,V=1.0370(3)nm^3,Z=2,μ=21.59cm^-^1,D~0=2.09g/cm^3,F(000)=628,最终偏差因子R=0.0371

Substitution of Ru3(CO)12 by heptene gave H3Ru3(CO)9(C7H11). The structure of the product is speculated by the anal. of IR, 1H NMR, 13C NMR, MS and elementary anal. The double bond in heptene was opened. An x-ray diffraction of the product has unequivocally established its structure. The cluster is triclinic space, and the space group is P1. a 0.9726(2) nm, b 0.9868(1) nm, c 1.1104(2) nm, a 103.22(1), b 89.91(1), g - 91.55(1)? Z = 2, m = 21.59 cm-1, dc = 2.09 g/cm3, F (000) = 628, R = 0.0371.
