Synthesis and characterization coordination of polymers of a new Cd(II) with bidentate flexible ligands

A new coordination polymer, [Cd(μ2-SCN)2(bibMe)]n (1), was prepared at room temperature by the reaction of appropriate salt of cadmium(II) with the flexible linker ligands 1,4-bis(imidazolyl) butane (bib) and methylimidazolyl)butane (bibMe). The compound was characterized by elemental analyses, IR spectroscopy and single crystal X-ray diffraction. In the polymeric structure of 1, the Cd(II) ion adopt the CdN4S2 pseudo-octahedral geometry and two bibMe ligands are coordinated to one central Cd(II) to form 2D framework with new topology (Point symbol: 39.410.52).
