Four coordination polymers derived from a one-pot reaction and their controlled synthesis

Author affiliations

Abstract

Four different Co(II) coordination polymers have been built by two flexible ligands 4,4′-dicarboxydiphenyl sulfone (4,4′-sdb) and 1,4-bis((1H-imidazol-1-yl)methyl) benzene (BMB) in a one-pot solvothermal reaction. The structures of 1 and 2 are new, and 3 and 4 have been reported. The crystal structures of 1–3 were obtained, namely [Co(4,4′-sdb)(BMB)]n (1), {[Co2(4,4′-sdb)2(BMB)]·2H2O}n (2), and [Co3(4,4′-sdb)2(DMF)(H2O)3]n (3), but 4 was confirmed by PXRD. Both 1 and 2 are 2D layered structures with sql topology and their point symbol is {44·62}. These complexes have been characterized by single crystal X-ray diffraction, infrared spectroscopy, thermogravimetry, elemental analysis, and powder X-ray diffraction measurements. By changing the synthesis conditions, four different Co(II) coordination polymers can be obtained respectively.
