| 摘要: 本文合成了一个新的配合物Co(H2CA)2(H2O)2(H3CA=三聚氰酸)，并通过元素分析、红外、荧光和单晶X-Ray射线进行了表征。标题化合物属于三斜晶系，P1空间群，a=0.503 83(7) nm，b=0.699 82(10) nm，c=0.911 08(13) nm，α=90.107(2)°，β=98.032(2)°，γ=110.788(2)°，V=0.296 92(7) nm3，Z=1，R=0.038 2。在配合物中，Co(Ⅱ)离子与三聚氰酸配体上的N原子，配位水的O原子配位，形成规则的平面正方形配位构型。相邻的2个Co(Ⅱ)平面四边形单元通过配体三聚氰酸上的氢键形成三维网状结构。室温荧光光谱测定表明该化合物在420 nm处有强的荧光发射。 |

| Abstract: A coordination polymer of Co(H2CA)2(H2O)2 has been synthesized and characterized by elemental analysis, IR, PL and X-ray single crystal diffraction (H3CA=cyanuric acid). The title complex crystallizes in triclinic with space group P1, a=0.503 83(7) nm，b=0.699 82(10) nm，c=0.911 08(13) nm，α=90.107(2)°，β=98.032(2)°，γ=110.788(2)°，and V=0.296 92(7) nm3, Z=1, R=0.038 2. In the title complex, each cobalt(Ⅱ) ion displays a regular square quadrangle geometry, with two N atoms from tow H2CA ligand, and two O atoms from two waters. Two adjacent Co(Ⅱ) square quadrangle units are linked into a 2D supramolecular network structure. The luminescent investigation reveals that the title complex exhibits strong emission of 420 nm at room temperature. CCDC: 870278. |
