| 摘要: 在溶剂热条件下制备了系列新配合物:[Cr2(tpc)2(HCOO)2(OH)2]·4H2O (1)、[Ba (tpc)2(H2O)2]n(2)、[Zn2(tpc)2(NO3)2]n(3)、[Pb (Htpc)(NO3)2]·2H2O (4)和[Rh (Htpc) Cl3]·CH3OH·H2O (5)(Htpc=2,2':6,2"-三联吡啶-4-羧酸)。X射线单晶衍射分析表明,有机配体呈4种不同的配位方式;配合物1~5通过C-H…O/N氢键和π…π相互作用形成了新颖的超分子网络。研究了这些配合物的发光性能。在365 nm紫外辐射下,晶体2~5分别呈现绿色、蓝色、蓝紫色和金色。 |

| Abstract: A series of complexes constructed by 2,2':6,2"-terpyridine-4-carboxylic acid (Htpc), namely[Cr2(tpc)2 (HCOO)2(OH)2]·4H2O (1),[Ba(tpc)2(H2O)2]n (2),[Zn2(tpc)2(NO3)2]n (3),[Pb(Htpc)(NO3)2]·2H2O (4), and[Rh(Htpc)Cl3]·CH3OH·H2O (5), have been prepared under solvothermal conditions. Single crystal X-ray analysis reveals that the organic ligands took four different coordination fashions in 1-5. Complexes 1-5 show novel supramolecular networks through rich C-H…O/N hydrogen bonds and π…π contacts. The luminescence of the complexes was investigated and under 365 nm ultraviolet radiation the crystals of 2-5 displayed green, blue, purple-blue, and golden colors, respectively. |
