Polymerization of C60 is realized under high temperature and high pressure. X-ray diffraction reveals a rhombohedral lattice structure in the product, and solid-state ^13C nuclear magnetic resonance spectroscopy confirms the formation of sp^3 bonds between C60 molecules. Specific heat is then measured over the temperature range of 300-2 K. It is found that its specific heat values are significantly less than those in fullerite within the region of 80-2K, and this huge reduction is attributed to the suppression of intermolecular librational modes in polymerized C60. An excellent fit to the experimental data over the entire temperature range is provided by a model, which needs to include only three-dimensional and two-dimensional translational modes in various contributions at different temperatures. 相似文献

An iron(Ⅱ) coordination polymer, Fe(Haip)2(H2O)2n (1, Haip = 5-ammoniumiso-phthalato), has been hydro/solvothermally synthesized and characterized by single-crystal X-ray diffraction, elemental analysis, infrared spectrum and magnetic measurement. Compound 1 crystalizes in monoclinic, space group P2/c with a = 6.9874(14), b = 9.960(2), c = 12.894(4), β = 117.47(2)°, Fe(C8H6NO4)2(H2O)2 , Mr = 452.16, V = 796.2(3)3 , Z = 2, D c = 1.886 g·cm-3 , μ = 1.017 mm-1 , F(000) = 464.0, 2.71<θ<28.42°, R = 0.0307, wR = 0.0840 and S = 1.005. Single-crystal X-ray diffraction analysis reveals that 1 features an infinite one-dimensional loop-like chain structure and Haip ligand in 1 is of zwitterionic form. Magnetic measurement results show the dominated ferromagnetic interactions among FeⅡ atoms. 相似文献

美国媒体近日报道说,苹果公司和谷歌公司分别通过智能手机操作系统收集用户行踪信息,用于建设其智能手机定位数据库。这些做法再次加重了人们对智能手机隐私性等问题的担忧。 相似文献
