摘要
The crystal structure of title complex has been determined by the method of X-ray single crystal diffraction.The crystal belongs to monoclinic space group C_(2/c)with the unit parameters a=2.8907(7), b=2.0431(5),c=1.5723(3)nm;β=115.67(2)°.The unit volume V is 8.36924(348)nm^3;Z=8, Dc=1,82g·cm^(-3),μ(MoK_α)=46.4cn^(-1); F(000)=4416.The final R is 0.083,Rw 0.088.The title complex con- sists of two univalent cations and one divalent anion.The anion has a cluster structure including six Sm^(3+). Coordination numbers of all six Sm^(3+)are eight,but their surroundings are different from each other.Two of them are decahedral array,and the others are octahedral array f the centroid of each pentacyclodienyl ring is taken as one point.
