摘　　要：合成了混合价态多核羰基钴离子对配合物[Co~Ⅰ(CO)(dppe-P,P′)_2]_2[Co~Ⅱ(μ-dppeo)Cl_6]{dppoo=双二苯基膦基乙皖Ph_2P(O)CH_2CH_2P(O)Ph_2}。用X射线衍射法测定了其晶体学参数为a=11.761(3),b=12.860(2),c=21.428(3) ,α=81.45(2),β=82.47(2),γ=79.84(2)°,三斜晶系,PI空间群,Co~Ⅰ和Co~Ⅱ具有不同的配位构型,量子化学计算结果解释了该配合物稳定的原因。The polynuclear cobalt carbonyl ion-pair complex with mixed valence states, [Co^1 (CO) (dppe-P, P')_2]_2 [CO_2~Ⅱ (μ-dppeo) Cl_6] [dppeo=Ph_2P (O) CH_2 CH_2 P (O) Ph_2] was synthesized. Its structure was determined by X-ray diffraction method. The crystallographie parameters of the title eomplex are: a=11.761 (3), b=12.860 (2), c=21.428(3) . α=81.45(2), β=82.47(2), γ=79.84(2)°; P1 space group, triolinio system. Co~Ⅰ and Co~Ⅱ possess different polyhedral eonfigurations, respectively. The stability of the title complex is explained by MO calculation.
