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,P(1)空间群,α=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.%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,a=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 0 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.
