摘 要：<正> The crystal structure of title complex has been determined by the method of X-ray single crystaldiffraction.The crystal belongs to monoclinic space group C2/cwith 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）nm3;Z=8,Dc=1,82g·cm-3,μ（MoKα）=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 Sm3+.Coordination numbers of all six Sm3+are eight,but their surroundings are different from each other.Two ofthem are decahedral array,and the others are octahedral array f the centroid of each pentacyclodienyl ring istaken as one point.
