product [Cu(HL)(L)]n (2) with Cu/(HL)/(L) = 1:1:1 displays a zigzag one-dimensional (1D) chain. The ditopic ligand is used also for the programmable self-assembly of a zero-dimensional (0D) mononuclear complex [Fe(HL)3] (3) and one-dimensional (1D) heterometallic multinuclear complex [AgFe(HL)3(NO3)]n (4). Complex 3 readily forms upon reaction of H2L with Fe(NO3)3 and NaHCO3 as the base. The reaction of 3
名为3-(3,5-二甲基-1 H-吡唑-4-基)戊烷-2,4-二酮的配体(H 2 L)与Cu(NO 3)2的反应可很好地产生两种类型的超分子同金属配合物-通过逐步去质子控制。以较低的NaHCO 3浓度为基准,产物[Cu(HL)2 ] 4(1)表现出二维(2D)菱形,Cu /(HL)= 1:2。但是,当在复合物1上进一步使用NaHCO 3时,产物[Cu(HL)(L)] n(2)(Cu /(HL)/(L)= 1:1:1)显示锯齿形一维(1D)链。对位配体还用于零维(0D)单核复合物[Fe(HL)3 ](3)和一维(1D)杂金属多核复合物[AgFe(HL)3(NO 3)] n(4)。当H 2 L与Fe(NO 3)3和NaHCO 3作为碱反应时,很容易形成络合物3。的反应3与所述第二金属的盐,产生复杂的4具有多孔梯形结构。配合物1,通过结合X射线晶体学,粉末X射线衍射,元素分析,热重分析和红外光谱
