二-2-吡啶基酮（dpk）可以以其活化的[（NC 5 H4）2C（OR）（OH）]或非活化的形式络合金属离子。在其活化形式中，其显示双核化行为，如化合物[{Cu 2 [（NC 5 H4）2C（OEt）O] Cl 3（EtOH）}2]和[{Cu 2 [（NC 5 H4）2C（OMe）O] Cl 3}∞]（其也具有卤素桥）所示。这些化合物已使用单晶X射线衍射进行结构表征。在其非活化形式中，它作为简单的双齿螯合物起作用。[{Cu（dpk）（NO3）2}∞]的X-射线衍射分析表明，该配合物具有阴离子桥连结构，铜中心与硝酸根桥连。还考虑了这些化合物的π堆积排列。
Di-2-pyridyl ketone (dpk) can complex metal ions in its activated [(NC5H4)2C(OR)(OH)] or non-activated form. In its activated form it displays a dinucleating behaviour as manifested by the compounds [{Cu2[(NC5H4)2C(OEt)O]Cl3(EtOH)}2] and [{Cu2[(NC5H4)2C(OMe)O]Cl3}∞](which also possess halide bridges). These compounds have been structurally characterised using single-crystal X-ray diffraction. In its non-activated form it acts as a simple bidentate chelate. The X-ray analysis of [{Cu(dpk)(NO3)2}∞] revealed an anion-bridged structure where bridging nitrato groups link the copper centres. The π-stacking arrangements of these compounds are also considered.
