| Abstract: The crystal of title compounds belongs to orthorhombic system with space group P212121 (No.19). The cell parmeters are a=1.432 16(3) nm, b=1.457 20(3) nm， c=3.005 85(6) nm, and V=6 273.0(2) nm3, Z=8, μ(Mo Kα)=22.21 cm-1， Dc=1.802 g·cm-3, F(000)=3 416.00, Finally R1=0.033 and wR2=0.073 (I>2.00σ(I)), S=1.023. Every center atom Sm(Ⅲ) is surrounded by the two aether chains, the title compound has ten-coordinate structure and the coordination polyhedron shows a Bicapped Square Antiprism. In the crystal, the title compound has the flack of double moleculars and non-symmetry. The anion ClO4- does not take part in the coordination. CCDC: 238709. |
