| 摘要: 本文合成了1个新的配位聚合物[Zn(apy)( μ-OH)NO3]n(apy=2-氨基嘧啶)，并且通过元素分析、红外、荧光、和单晶X-射线进行了表征。标题化合物属于单斜晶系，P21/c空间群，a=0.715 48(14) nm，b=1.850 5(4) nm，c=0.645 68(13) nm，β=110.24(3)°，V=0.802 1(3) nm3，Z=4，R=0.028 4。在化合物中，每个Zn(Ⅱ)离子与氨基嘧啶配体的1个N原子、硝酸根的1个O原子，以及2个羟基氧原子配位，并展示出扭曲的四面体几何构型。2个相邻的Zn(Ⅱ)四面体单元通过羟基氧原子连接形成一维链状结构，该一维链进一步通过氢键和π-π堆积作用形成三维网状结构。室温荧光光谱测定表明该化合物在392 nm处有强的荧光发射。 |

| Abstract: A coordination polymer of [Zn(apy)( μ-OH)NO3]n(apy=2-aminopyrimidine) has been synthesized and characterized by elemental analysis, IR, PL and X-ray single crystal diffraction. The title complex crystallizes in monoclinic with space group P21/c, a=0.715 48(14) nm, b=1.850 5(4) nm, c=0.645 68(13) nm, β=110.24(3)°, and V=0.802 1(3) nm3, Z=4, R=0.028 4. In the title complex, each zinc(Ⅱ) ion displays a distorted tetrahedral geometry, with one N atom from apy and one O atom from nitrate anion, and the other O atoms from hydroxy anions. Two adjacent Zn(Ⅱ) tetrahedral units are linked into a 1D chain by O atoms from hydroxy anions, which were further connected by hydrogen bonds and π-π stacking to form a 3D supramolecular network structure. The luminescent investigation reveals that the title complex exhibits strong emission of 392 nm at room temperature. CCDC: 759947. |
