摘要(Abstract)：
无水YbCl3与三倍量的LiNPh2 在四氢呋喃 (THF)中反应 ,合成了中性均配型稀土胺化物Yb(NPh2 ) 3(THF) 2 。产物经元素分析、红外光谱表征 ,并测定了其晶体结构。配合物属单斜晶系 ,P2 1 /n空间群 ,晶胞参数为a =1 2 0 5 2 ( 2 )nm ,b =1 9369( 3)nm ,c =1 65 2 3( 2 )nm ,β =92 79( 1)°,V =3 85 2 4( 9)nm3,Z =4,Dc=1 417g·cm- 3,μ =2 4 67cm- 1 (MoKα) ,F( 0 0 0 ) =1668,R =0 0 36,Rw=0 0 39。3个二苯胺基的氮原子和两个THF的氧原子与金属镱配位 ,形成五配位的扭曲的三角双锥几何构型。平均的Yb—N键长为 0 2 2 19( 6)nm。
