title: Four coordination polymers derived from a one-pot reaction and their controlled synthesis.
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 and are new, and and have been reported. The crystal structures of were obtained, namely [Co(4,4'-sdb)(BMB)]n (), {[Co2(4,4'-sdb)2(BMB)]·2H2O}n (), and [Co3(4,4'-sdb)2(DMF)(H2O)3]n (), but was confirmed by PXRD. Both and are 2D layered structures with sql topology and their point symbol is {4(4)·6(2)}. 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.
