本文采用2,2-联二吡啶与氧心三核物[M~3O(C~2H~5COO)~6(H~2O)~3]·NO~3(M=Fe;Cr)在乙腈中反应的方法制备了两个簇合物:[Fe~4O~2(C~2H~5COO)~7(bipy>~2]·[Fe~2Cr~2(C~2H~5COO)~7(bipy>~2]·ClO~4(2).从测定的单胞参数可确定它们为异质同晶,进而测定了簇合物1的结构.晶体属三斜晶系,空间群PI,单胞参a=1.5328(2),b=1.6325(2),c=1.3017(2)nm,a=113.49(1),β=115.12(1),γ=94.11(1)°;Ⅴ=2.5882nm^3,D~c=1.51g.cm^-3,Z=2,R=0.063,R~w=0.094.

Fe, M' = Ce) are prepared by the reaction of 2, 2'-bipyridine with [M3O(EtCO2)6(HO)3]NO3 (M = Fe, Cr) in MeCN. The cell parameters of the 2 compounds show that they are isomorphous. The crystal structure of [Fe4O2(EtCOO2)7(bipy)2]ClO4 was determine by single crystal x-ray diffraction. It crystallizes as triclinic, space group P1, a 1.5328(2), b 1.6325(2), c 1.3017(2) nm, a 113.49(1), b 115.12(1), g 94.11(1)? Z = 2, R = 0.063, Rw = 0.094.
