Synthesis, Structure, and Fluorescence of a Novel Samarium Compound

Synthesis, Structure, and Fluorescence of a Novel Samarium Compound A novel samarium compound, [Sm(Phen)2(H2O)5]2(Phen)2(Bipy)Cl6 · 7H2O (I) (Phen = 1,10-phenanthroline and Bipy = 2,2'-bipyridine), was prepared by a solvothermal reaction. The crystal structure of I was characterized by X-ray single-crystal diffraction method (CIF file CCDC no. 1025736). Compound I is an isolated structure with the samarium ions possessing a nine-coordinated distorted monocapped square antiprism geometry. There are abundant hydrogen bonding and π–π stacking interactions which connect the molecules together to yield a three-dimensional (3D) supramolecular structure. The fluorescence spectra data reveals that I can display the characteristic emission 4 G 5/2 → 6 H J transitions (J = 5/2, 7/2, 9/2 and 11/2, respectively) of Sm3+ ions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Coordination Chemistry Springer Journals

Abstract

A novel samarium compound, [Sm(Phen)2(H2O)5]2(Phen)2(Bipy)Cl6 · 7H2O (I) (Phen = 1,10-phenanthroline and Bipy = 2,2'-bipyridine), was prepared by a solvothermal reaction. The crystal structure of I was characterized by X-ray single-crystal diffraction method (CIF file CCDC no. 1025736). Compound I is an isolated structure with the samarium ions possessing a nine-coordinated distorted monocapped square antiprism geometry. There are abundant hydrogen bonding and π–π stacking interactions which connect the molecules together to yield a three-dimensional (3D) supramolecular structure. The fluorescence spectra data reveals that I can display the characteristic emission 4 G 5/2 → 6 H J transitions (J = 5/2, 7/2, 9/2 and 11/2, respectively) of Sm3+ ions.
