Two cyano|bridged complexes {-2[Fe(CN)-6]}-∞(L=NH-2CH-2CH-2CH-2OH(ampt)(1),NH-2CH-2CH(CH-3)OH(amtt)(2)) and cyanobridged Ni+Ⅱ-6Fe+Ⅱ cluster [Fe(CN—Ni(tetren))-6](ClO-4)-8(tetren)(3) were synthesized,and have been characterized by elemental analysis and IR spectrum.The experimental results show that the oxide state of Fe is changed from Fe+Ⅲ to Fe+Ⅱ after the synthesis reaction.The magnetization versus T and magnetic susceptibility of (2) were measured and showed that the interaction between Cu+Ⅱ ions separated by diamagnetic low spin Fe+Ⅱ is weak antiferromagnetic.

從7月中旬以来,美国之外最大的电影市场一部美国电影都没有上映,放映的是中国真人动画奇幻电影《捉妖记》,主角是来自中国古代的小妖。指导本片的是曾导演《怪物史瑞克3》的许诚毅,《捉妖记》7月16日在中国上映,立刻打破了记录:7月18日周六的票房达到2980万美元,成为中国电影单日最高票房,超过了很多西方大片的首日票房。中国更大更好的本土电影和不断增加的观众创造了足够大的电影市场,完全可与好莱坞相抗衡。
