摘要: 以1,2-二(4H-1,2,4-三唑)乙烷(btre)和3个二元羧酸1,3-金刚烷二酸(H2adc)、对苯二甲酸(1,4-H2bdc)和邻苯二甲酸(1,2-H2bdc)为配体,在室温下合成了3个锌配位聚合物{[Zn(μ2-btre)(μ2-adc)]H2O}n(1·H2O)、[Zn2(μ2-btre)(μ2-1,4-bdc)2(H2O)2]n(2)和[Zn(μ2-btre)(μ2-1,2-bdc)]n(3)。测试了3个配合物的晶体结构,并用红外光谱、元素分析和粉末衍射对其进行表征。晶体结构测试表明,1为2D(4,4)网格结构,π-π作用将相邻的2D网格连接成3D结构。配合物2和3分别是3D和2D(4,4)网格结构。另外,研究了3个配合物的热稳定性和室温下的固体荧光。 |

Abstract: Three new coordination polymers, {[Zn(μ2-btre)(μ2-adc)]·H2O}n (1·H2O),[Zn2(μ2-btre)(μ2-1,4-bdc)2(H2O)2]n (2) and[Zn(μ2-btre)(μ2-1,2-bdc)]n (3) were synthesized at room temperature condition and characterized by IR spectra, elemental analyses, single-crystal and powder X-ray diffractions (btre=1,2-bis(1,2,4-triazol-4-yl) ethane, adc=1,3-adamantanedicarboxylate, 1,4-bdc=1,4-benzenedicarboxylate, 1,2-bdc=1,2-benzenedicarboxylate). Structural analyses reveal that complex 1 exhibits a 2D (4,4) network, and the adjacent 2D (4,4) networks are connected into 3D network by strong π-π interactions. The structure of 2 and 3 are 3D and 2D (4,4) network, respectively. Thermal stabilities and the solid-state luminescence at room temperature of 1, 2 and 3 were investigated. |
