【摘要】 以5-羟基-2-吡啶羧酸为配体,通过水热法与过渡金属盐合成了5个配合物,其分子式分别为[M(HL)2(H2O)2](M=Zn,1;Mn,2;Co,3;Ni,4),[Cu(HL)2](5)。由元素分析,红外光谱,X-射线单晶衍射对化合物1~5的结构进行了表征。化合物1~5为单核结构的配合物,它们均通过氢键形成了三维超分子结构。测试了配合物1的光致发光及1~5的热稳定性。研究发现,配合物1发光归因于配体内的跃迁。更多还原

【Abstract】 Five transition metal complexes based on the 5-hydroxy-pyridine-2-carboxylic acid(H2L) were synthesized under hydrothermal conditions, namely, [M(HL)2(H2O)2](M=Zn, 1; Mn, 2; Co, 3; Ni, 4), [Cu(HL)2](5).Compounds 1~5 were structurally characterized by the elemental analyses,infrared spectra, and single crystal Xray diffractions. The structural analyses show that 1~5 are discrete mononuclear complexes, which are extended to form the 3D supramolecular frameworks by hydrogen bonds interactions. The solid-state photoluminescence of1 and thermal properties of 1~5 were further explored, respectively. CCDC: 949732, 1; 949731, 2; 1056084, 3;1056085, 4; 1056086, 5.更多还原
