Four new metal–organic coordination polymers, [Cd2(sbpdc)2(bpy)] (1), [Cd(sbpdc)(bpp)1/2] (2), [Co(sbpdc)(bpy)] (3) and [Co(sbpdc)(bpp)(H2O)] (4) (H2sbpdc = sulfone-4,4′-biphenyldicarboxylic acid, bpy = 4,4′-bipyridine, bpp = 1,3-bis(4-pyridyl)propane) have been synthesized under solvothermal conditions and characterized by single-crystal X-ray diffraction, elemental analysis and IR spectra. Compound 1 displays a 3D 6-connected twofold interpenetrated net with pcu topology, while 2 contains 1D infinite Cd-O-Cd chains. Compound 3 is a new 3D binodal network with the point symbol of (63) (67 ⋅ 83), whereas compound 4 has a 1D double chain. Moreover, the PXRD, TGA, luminescent and magnetic property were also investigated.
We have successfully synthesized four new coordination polymers under solvothermal conditions. They have intriguing structures and topologies. The different coordination modes of the carboxylate ligand have a significant effect on the structures.Figure optionsDownload as PowerPoint slideHighlights
► Four new coordination polymers were prepared by hydrothermal method.
► The coordination modes of the ligand have effect on the structures.
► Both of two cadmium coordination polymers emit intense fluorescence.
► Compound 3 reveals antiferromagnetic exchange interactions.
