In this paper, the synthesis of bis (2-methoxyethylcyclopentadienyl) samarium iodide (Cp2’SmI (Ⅰ) (Cp ’= CH_3OCH_2CH_2C_5H_4) with intramolecular oxygen atom coordination and the solvation of 2- Methoxyethylcyclopentadienyl Samarium Diiodide (Cp’SmI_2 · 2THF (Ⅱ)). Complexes (I) and (II) were identified by elemental analysis and mass spectrometry. And got their single crystal. The structural studies show that the crystal belongs to the space group P2_12_12_1, with unit cell parameters of a = 11.074 (4) (?), B = 12.929 (9) and c = 12.269 (4) And two cyclopentadienyl groups, the oxygen atoms of the two ether groups are coordinated with an iodine atom to form a monomer structure, and the coordination number of Sm (III) is 9. There are four monomer molecules in the unit cell. The crystal belongs to the P2_1 / c space group. The unit cell parameters are a = 16.304 (6) (?), B = 8.335 (2) ) (?),? = 111.8 (1) °. Each samarium in the crystal (II) is coordinated to form a monomeric structure through a cyclopentadienyl group, an oxygen atom on an ether group substituent, an oxygen atom of two tetrahydrofuran and two iodine atoms, and the complex of Sm (III) The number of digits is 8. The unit cell contains 4 monomer molecules.
