| 摘 要： | Cd(NO3)2·4H2O与配体4′,5′-二氮-9′-(4，5-二(硫乙基)-1，3-二硫杂环戊烯-2-叶立德)-芴(L)在甲醇和二氯甲烷的混合溶剂中生成配合物Cd(NO3)2(L)2。晶体的空间群是Pbcn(#60)，晶体学参数分别是a=1.578 7(2) nm，b=0.987 96(11) nm，c=2.719 5(3) nm。V=4.241 6(8) nm3，Z=4。2个硝酸根离子各提供1个氧原子，2个配体L各提供2个氮原子，形成了镉的6配位结构。晶体结构显示分子通过平面之间的π-π相互作用沿b轴形成柱状结构，这些柱通过中心原子镉(Ⅱ)的配位连接形成二维层状结构，再通过2个硫乙基上的短距离S…S接触进一步形成了三维结构。对其 1H NMR、UV-Vis和荧光光谱进行了研究。

| Abstract: | Reaction of Cd(NO3)2·4H2O with 4',5-diaza-9'-(4,5-bis(ethylthio)-1,3-dithiole-2-ylidene)-fluorene (L) in
a mixture of methanol and dichloromethane forms a coordination compound Cd (NO3)2(L)2. The crystal is in orthorhombic space group Pbcn(#60) with crystallographic parameters a=1.578 7(2) nm, b=0.987 96(11) nm, c=2.719 5(3) nm, V=4.241 6(8) nm3 and Z=4. The coordination sphere of Cd(Ⅱ) is satisfied by coordination of two oxygen atoms from two nitrate ions and four nitrogen atoms from two ligands L. Crystal structure shows that the molecules are stacked via plane to plane π-π interactions forming columns along the b axis. These columns are linked to form two-dimensional layer structure by the coordination connection of the center atom Cd(Ⅱ). There are very short S…S contact (0.329 7 nm) between two ethylthio sulfur atoms, so that a three-dimensional structure is further completed. 1H NMR, UV-Vis and fluorescent spectra of the title compound were studied.
