N-杂环卡宾银配合物的合成与表征

Synthesis and Characterization of N-Heterocyclic Carbene Complex of Silver(I)

由N-杂环卡宾配体L(L=1,3-双(苄基)苯并咪唑盐酸盐)与Ag2O反应,得到银卡宾配合物(1),通过核磁、元素分析对化合物进行全面表征。并采用溶剂挥发法得到化合物(1)的单晶,利用X-射线单晶衍射测定和研究了化合物(1)的晶体结构,晶体结构数据:单斜晶系,空间群P2(1)/c,a=9.144(8),b=9.518(9)°,c=20.789(19)°,α=90°,β=94.307(13)°,γ=90°,Z=4,V=1804(3)3。

Ag（I）-NHC complex（1） was synthesized from reacting ligand （L=3-bis （benzyl） benzimidazolium chloride hydrate） with Ag2 O and characterized by NMR and elemental analyses.The single crystals of complex 1 were growth by volatilization methods and characterized by X -ray single crystal diffraction analysis.Crystal data were Monoclinic, space group P2（1）/c, a=9.144（8）？, b=9.518（9）°, c=20.789（19）？, α=90°,β=94.307（13）°,γ=90°, Z=4, and V=804（3）？3.
