Synthesis, Structure, and Luminescent Properties of a Cadmium(II) Supramolecular Coordination Complex

Resumo

A new supramolecular complex [Cd(dcbpy)(im)₂(H₂O)₂] · 3H₂O (H₂dcbpy = 4,4'-dicarboxy-2,2'-bipyridine, im = imidazole) has been prepared under hydrothermal conditions. Its crystal structure is determined with single crystal X-ray diffraction. Cd²⁺ atom is six-coordinated by one dcbpy ligand, two imidazole and two water molecules. Each [Cd(dcbpy)(im)₂(H₂O)₂] unit is connected to neighboring units through intermolecular O–H···O hydrogen bonds to form a three-dimensional supramolecular network structure. A topology method has been used to simplify the network. The stability and luminescent properties of the complex obtained have been investigated.
