Abstract: A new supramolecular complex [Cd(dcbpy)(im)<subscript>2</subscript>(H<subscript>2</subscript>O)<subscript>2</subscript>] · 3H<subscript>2</subscript>O (H<subscript>2</subscript>dcbpy = 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. Cd<superscript>2+</superscript> atom is six-coordinated by one dcbpy ligand, two imidazole and two water molecules. Each [Cd(dcbpy)(im)<subscript>2</subscript>(H<subscript>2</subscript>O)<subscript>2</subscript>] 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. [ABSTRACT FROM AUTHOR]
