采用新的单配体Ag-Amidn（1）（HAmidn：2-氨基-4，5-咪唑二甲腈）成功地制备了一种前所未有的具有三维倍频活性的银金属有机骨架（MOF）。咪唑和腈氮原子的协同配位导致手性三螺旋占非中心对称空间群，它们连接在一起形成罕见的10（3）拓扑结构。Ag-Amidn（1）具有较高的热稳定性和不溶性，是一种潜在的二阶非线性光学材料。
An unprecedented 3-D SHG-active metal-organic framework (MOF) of silver(I), Ag-Amidn (1) (HAmidn: 2-amino-4,5-imidazoledicarbonitrile), has been successfully prepared by employing the new single ligand. The cooperative coordination of the imidazole and carbonitrile N atoms leads to the chiral triple helices accounting for the noncentrosymmetric space group, which are linked together to form a rare 10(3) topological structure. Ag-Amidn (1) with high thermal stability and insolubility may be considered as a potential second-order NLO material.
