摘要: 在浓盐酸水溶液中,碘化N,N-二甲基-1,5-二氮杂环[3.2.1]辛烷([3.2.1-Me2dabco]I2)和碘化1-氨基-1,4-二氮杂环[2.2.2]辛烷([2.2.2-NH2dabco]I)与氯化铜反应得到2种有机-无机杂化铜化合物[3.2.1-Me2dabco][CuCl4](1)和[2.2.2-NH2dabco][CuCl4](2)。X射线单晶结构衍射证实化合物1和2中的无机阴离子是[CuCl4]2-四面体。化合物1和2表现出可逆的热致变色现象,随着温度升高,它们的颜色从黄色变为红色,这应该是由[CuCl4]2-四面体的变形引起的。 |

Abstract: Reactions of N,N-dimethyl-1,5-diazabicyclo [3.2.1]octane iodide ([3.2.1-Me2dabco]I2) and 1-amino-1,4-diazabicyclo [2.2.2]octane iodide ([2.2.2-NH2dabco]I) with anhydrous copper chloride in concentrated HCl aqueous solution afforded two organicinorganic hybrid compounds [3.2.1-Me2dabco] [CuCl4] (1) and [2.2.2-NH2dabco] [CuCl4] (2), respectively. The single-crystal X-ray diffraction revealed that the inorganic component in compounds 1 and 2 was a distorted tetrahedral geometry [CuCl4]2-. Compounds 1 and 2 showed an intriguing reversible thermochromism with color change from yellow to red which may be derived from the deformation of [CuCl4]2- tetrahedron. |
