| 摘要: 合成了单电子还原混合价杂多化合物[C10H10N]4HGeMo12O40,并由元素分析、IR、UV进行了表征。单晶X射线分析表明,属单斜晶系,空间群P21/n,晶胞参数a=1.4803(3),b=1.2582(3),c=1.7712(4)nm,β=98.31(3)°,V=3.264(16)nm3。由4296个可观察衍射点进行全矩阵最小二乘法修正后,可靠性因子R=0.0646。变温ESR研究表明随温度降低单电子离域程度减小。 |

| Abstract: The single electron reduced compound, [C10H10N]4HGeMo12O40, was synthesized and characterized by elements analysis, IR and UV spectra. The crystal structures analysis show space group P21/n,a=1.4803(3),b=1.2582(3),c=1.7712(4)nm,β =98.31(3)°,V=3.264(16)nm3. The final reliability factor is R=0.0646 for 4296 observed reflections. The ESR data indicate that the single electron in the anions is delocalized among the molybdenum atoms. |
