Abstract:The new samarium ( Ⅲ ) complex [ Sm ( sap ) (HMDS) (THF) ] 2 ( sap = salicylidene-2-aminophenol ; HMDS = Hexamethyldisilazane ) was synthesized and characterized by single-crystal X-ray diffraction. The crystal is of monoclinic, space group P2 1/n with a=1.27245(12),b=1.91087(18),c=1.40749(13)nm,β=111.6650(10)°,V=3.1805(5)nm3,Z=2,M=1320.23,μ=1.95mm^-1 ,the final R =0.036 and wR =0. 111 for 5 016 observed reflections (I 〉 2σ(I) ). The coordination geometry of samarium atom is distorted octahedron, coordinated by two nitrogen atoms and one O atom from one sap ligand, one O atom from another sap ligand, and one O atom from a THF, and a N atom from a HMDS.
Keywords:samarium complex  bisnuclear  crystal structure  synthesis
