A Cu(II) complex of 4-phenyl-3,5-dicarboxylic-pyridine (HL2), [Cu(HL2)Py], was isolated unexpectedly during studying coordination reaction of 3,5-dicarboxylic-1,4-dihydropyridine-4-phenyl ligand (HL1) with copper(II) nitrate by solvothermal method. Crystal structure of the [Cu(HL2)Py] was determined by single-crystal X-Ray diffraction and its phase purity and thermal stability was evaluated by PXRD
在研究3,5-二羧酸-1,4-的配位反应过程中意外地分离出了4-苯基-3,5-二羧酸-吡啶(HL 2)的Cu(II)络合物[ Cu(HL 2)Py ]。溶剂热法与硝酸铜(II)形成二氢吡啶-4-苯基配体(HL 1)。通过单晶X射线衍射确定[ Cu(HL 2)Py ]的晶体结构,并分别通过PXRD和TGA评价其相纯度和热稳定性。此外,以更多地了解[ Cu(HL 2)Py],对其几何和电子结构进行了实验和理论研究。最后,通过DFT计算研究了HL 1的氧化机理。
