| 摘要: 单取代环戊二烯(C5H5R)(R=n-Butyl(1),Benzyl(2),n-Propyl(3),Allyl(4))分别和Mo(CO)6反应,生成4个新的环戊二烯基钼双核羰基配合物(C5H4R)2Mo2(CO)6(R=n-Butyl(5),Benzyl(6),n-Propyl(7),Allyl(8))。配合物5～8通过元素分析,IR,1H NMR,热重进行了表征,并用X-ray单晶衍射法测定了配合物5和6的晶体结构。晶体结构显示配合物5属于单斜晶系,P21/c空间群,配合物6属于三斜晶系,Pl空间群;热重分析表明配合物5和6分别处于107和162℃以下温度时很稳定。 |

| Abstract: Monsubstituted cyclopentadienes (C5H5R) (R=n-Butyl (1), Benzyl (2), n-Propyl (3), Allyl (4)) reacted with Mo(CO)6 to give four new dinuclear cyclopentadienyl molybdenum carbonyl complexes (C5H4R)2Mo2(CO)6 (R=n-Butyl (5), Benzyl (6), n-Propyl (7), Allyl (8)), respectively. The complexes 5～8 were characterized by elemental analysis, IR, 1H NMR spectrum, and TG. The crystal structures of 5 and 6 were determined by X-ray single crystal diffraction. The structures show that complex 5 crystallizes in monoclinic system with space group P2l/c and complex 6 is triclinic crystal system with space group Pl.The TGanalysis shows that the complexes 5 and 6 are stable below 107 and 162 ℃, respectively.
