The title compound, di--chloro-bis[(5-trimethylsilylcyclopentadienyl)samarium(III)], [SmCl2(C8H13Si)4], which has been characterized by single-crystal X-ray diffraction, is isostructural with its ytterbium analogue. The geometrical parameters of the lanthanide atoms are compared in the two compounds. Results and conclusions reported for [Yb(5-C5H4SiMe3)2(-Cl)]2 are entirely corroborated by the present structure analysis.
