Biaqua-trichloroacetate-samarium dihydrate, [Sm(CCl3COO)3(H2O)2]-2H2O, Mr=707.54, orthorhombic, space group Pnne, with a = 19.158(5), b = 22.176(4), c= 9.798(4)A, Z= 8, V= 4162.7A3.F{000)= 2696,λ(MoKα)=0.71069A, Dx = 2.258 g/cm3, final R=0.061. The title compound has non-molecular structural character, and its structural units Sm(μ-CCl3COO)s/2-(H2O>2 constitute 2-dinensional infinite chains of Sm(μ-CCl3COO)4Sm(μ-CCl3-COO)2Sm.The Sa(Ⅲ) atom in each unit is bound to two O atoms from aqua-molecules and six 0 atoms from six bridging CCl3COO groups (four of which are shared with the SB atom of another unit, two shared with the Sm atom of a third unit) forming a square antiprism.
