Synthesis, structure and properties of a new copper (II) complex, [Cu2(4,4′-bpy)5(H2O)4](ClO4)4(4,4′-bpy)(DMF)2(H2O)2

A new copper (II) complex with formula [Cu2(4,4′-bpy)5(H2O)4](ClO4)4(4,4′-bpy)(DMF)2(H2O)2 has been synthesized by reaction of 4,4′-bpyridine (4,4′-bpy) with Cu(ClO4)2. While strong hydrogen bonds play central roles in the formation of the 3D structure, the combined influence of the weak interactions such as C–H⋯O bonds, anion⋯π and C–H⋯π interactions are also evident in the structure. The preliminary investigation on the thermal property of the complex is presented.

Various solvent and anions (H2O, ClO4−, DMF, 4,4′-bpy) were encapsulates inside the channels (channel a, b, c and d) of the 3D networks which act as a host to stabilize the structure.Figure optionsDownload as PowerPoint slide
