A Cu(II) complex [Cu(bipy)(H₂O)₂(SO₄)]_n (bipy = 2,2′-bipyridine) was synthesized by hydrothermal method and characterized structurally by elemental analyses, single crystal X-ray diffraction, infrared spectra, and thermogravimetry and differential scanning calorimetry. The Cu(II) was hexacoordinated by two N atoms from bipy, two O atoms from different sulfate radical anions, and two O atoms from two water molecules, forming a slightly distorted octahedral geometry, and bridged by sulfato groups into polymeric chains. Under the condition of physiological pH, the interaction mechanism between the complex and hsDNA was explored with acridine orange as a fluorescence probe by spectroscopic methods. The binding modes between the complex and hsDNA were the electrostatic and embedded modes.

含2,2'-联吡啶的铜（II）配合物的水热合成，结构表征及其与DNA的相互作用机理。

Cu（II）络合物[Cu（bipy）（H ₂ O）₂（SO ₄）] _n（bipy = 2,2'-bipyridine）是通过水热法合成的，并通过元素分析，单晶X射线衍射，红外光谱，热重分析和差示扫描量热法进行结构表征。Cu（II）由来自联吡啶的两个N原子，来自不同硫酸根自由基的两个O原子和来自两个水分子的两个O原子进行六配位，形成略微扭曲的八面体几何形状，并通过硫酸根基团桥接成聚合物链。在生理pH条件下，以a啶橙为荧光探针，探讨了配合物与hsDNA的相互作用机理。复合物与hsDNA之间的结合模式是静电和嵌入模式。
