Structures of dioxobipyridil-12-crown-4 and its complexes with silver (I) and copper (II) cations

The structures of dioxobipyridil-12-crown-4 (bpy-CO-crown) and its complexes with copper (II) and silver (I) cations have been determined using single crystal X-ray-diffraction. The results have been compared with the literature data on the complexes of dcmbpy and its complex with silver (I) and copper (II) cations.
