2Syntheses and Crystal Structures of Benzyl-and Cyclopentyl-Cyclopentadienyl Sodium Tetrahydrofuranate Complexes显示文摘The present paper covers syntheses and crystal structures of benzyl- and cy-clopentyl-cyclopentadienyl sodium tetrahydrofuranate complexes C6H5CH2C5H4Na·THF (1) and C5H9C5H4Na°THF (2). X-ray diffraction data of the title compounds were collected at a low temperature (about 210K). Structures of both the crystals belong to monoclinic space group P21/n with α=0. 9316(3) nm, b=1. 5161(4) nm, c= 0.9791(3) nm, β=91. 06(3)°Z=4 for (1) and α=1. 6120(7) nm, b=0. 9370(3) nm, c=1. 8475(7) nm, β=109.52(3)°Z = 8 for (2). Both structures were solved by using direct methods and refined by block-matrix least-squares to final values of R = 0. 044 for 520 observed reflections (1) and R = 0. 067 for 921 observed reflections (2). In the crystals the tetrahydrofuranate complexes C6H5CH2C5H4Na·THF and C5H9C5H4Na·THF adopt a puckered chain structure with η5-(C6H5CH2)C5H4 and η5-(C5H9)C5H4 rings connected by a bridge Na (THF) unit.Zhang Bin (Department of Chemistry, Heilongjiang University, Haerbin)Jin Zhongsheng, Wang Yuling, Wei Gecheng and Chen Wenqi (Changchun Institute of Applied Chemistry, Chinese.

7Crystal and Molecular Structure of Mo_2[(μ_2-S)SCNEt_2]_2(S_2CNEt_2)_2显示文摘Crystal structure of the title complex was determined by X-ray diffraction method. It crystallizes in space group P21/n with cell dimensions:α=10. 041(5) , b=10. 719(4) , c= 1. 5671(6) nm, β=104. 36(3)°. The structure was solved by Patterson method. The final residual factor is R=0. 050.Sun Chunting, Huang Qijun, Li Shuqin and Wang Tiegang(Department of Chemistry, Jilin University, Changchun)Zhang Guangren, Qu Xiangbang, Tang Zhongkun, He Guoqiang and Shen Yankui (Logistics Engineering Institute, Chongqing) Jin Zhongsheng and Wei Gecheng (Changchun Institute of Applied Chemistry, Changchun) 1991Chemical Research in Chinese Universities1991,7,2:0
