摘要
(C5H4CH3)3Ho和(C5H4CH3)2Ho(C5H5)与5-苯基四唑(HN4CPh)在THF中反应,得到复合产物[(C5H4CH3)2HoN4CPh]2·[(C5H4CH3)(C5H5)HoN4CPh]2,该晶体属三斜晶系,P1空间群,晶胞参数为a=9.386(3),b=13.071(3),c=16.571(2)A,a=86.90(1),β=74.61(2),γ=77.30(2)°,V=1912.2(8)A3,Z=1,Dc=1.602g/cm3,Mr=922.61,μ=41.92cm-1,F(000)=896,最终偏离因子R=0.041,Rw=0.056.晶体数据显示,在同一个晶胞里有两个组成不同的分子,每一个分子都是具有对称中心的四唑基桥二聚体结构,其桥环单元-HoN3HoN3-是平面型的。每个钬原子分别被两个茂基和3个四唑基氮原子配位,形成1个边桥变形四面体构型。
