邻氨基酚缩水杨醛钐配合物的合成和结构表征

Synthesis and crystal structure of samarium complex with salicylidene-2-aminophenol

合成了一个新的钐双核配合物[Sm(sap)(HMDS)(THF)]2(sap=水杨醛缩邻氨基酚,HMDS=六甲基硅胺基)并测定了其晶体结构,晶体属于单斜晶系,空间群P21/n,a=1.27245(12),b=1.91087(18),c=1.40749(13)nm,β=111.6650(10)°,V=3.1805(5)nm3,Z=2,Mr=1320.23,μ=1.95mm-1,对于I>2σ(I)的5016个衍射点的最终R=0.036,wR=0.111,钐原子与一个sap配体的一个氮原子和两个氧原子以及另一个sap配体桥连的氧原子,一个四氢呋喃的氧原子,一个六甲基硅胺的氮原子配位,形成了扭曲八面体的配位环境.

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.
