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 (MoK_α), c = 1.5723 (3) nm, and β = 115.67 (2) °. The unit volume V is 8.36924 (348) nm~3; = 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 arrays, and the others are octahedral arrays f the centroid of each pentacyclodienyl ring istaken as one point.
