摘要
报导了一种新型(C_5H_5)3Nd(THF)晶体结构,晶体属单斜晶系,C2/c空间群,晶胞参数为a=12.839(7),b=10.520(3),c=26.599(9),β=98.50°,V=3553(3),Z=8,D_c=1.54g/cm ̄3,M_r=411.63,μ=29.29cm(-1),F(000)=1640,最终偏离因子为R=0.061,Rw=0.073。新晶体结构在空间群、晶胞参数和Z值上均明显不同于前面的报导,在Cp3Ln·THF系列化合物中,这是首次发现同一化合物可以用两种分子堆积方式结晶。
From the mixture solution of(C_5H_5)_3Nd and (C_5H_4Me)_3Nd in THF (tetrahydrofuran),crystals of the so far unreported modification (C_5H_5)_3Nd· THF)I) were obtained.The new structure differs markedly from the previously reported data for the same compound (Ia) (from pure solution) in cell dimensions parameters, space group and Z-value.
