To cite this article: Daofu Liu (2015): Syntheses, crystal structure and characterization of two Mn(II) coordination polymers based on 4,4'-sulfonyldicarboxylic acid and length modulated bisimidazole ligands, Journal of Coordination Chemistry, Two new coordination polymers based on imidazole-containing ligands with different spacers, {[Mn(4,4'-sdb)(L 1 ) 0.5 ]·0.5(L 1 )} n (1) and [Mn(4,4'-sdb)(L 2 )] n (2) [4,4'-H 2 sdb = 4,4'-sulfonyldicarboxylic acid, L 1 = 1,4-bis(1-imidazolyl)benzene and L 2 = 4,4′-bis(1-imidazolyl)bibenzene], have been synthesized under hydrothermal conditions.Complex 1 shows a two-dimensional layer structure with a sql topological net. Complex 2 features a three-dimensional framework with CdS topology. In addition, the fluorescent properties of 1 and 2 have been investigated.
