Using K3Fe(CN)6, N, N - dimethylacetamide (DMA) and Sm(NO3)3·6H2O, the title complex [Sm(DMA)2(H2O)4Fe(CN)6·5H2O]n has been synthesized and characterized with elemental analysis, IR spectra and X - ray crystal structure.
The title complex was obtained from a solution of chloroformand methanol (1:1) mixture solvent and mbtea which was reacted with solid[Cu(CH_3CN)_4]ClO_4.The conductivity,electronic spectra and infrared spectra ofthe complex were measured.
The fractional coordinates of all hydrogenatoms are obtained by difference Fourier method and the final residual factor is R=0.058. The result shows that the title compound is β-epoxy containing iso-arteannuin B_2.
In Such a background and with the knowledge of the lack of through study in the emotion and value education, the author chose " emotion, attitude and value education in junior middle school" as the title of study.
The eight ancient Chinese words in semantic field of title which contains the meaning of elder in the relationship of marriage can be divided into five groups according to their character forms,that is "gong"(公),"jiu"(舅),"zhang"(章),"zhong"(锺),and "zhen"(祯).
