Two new coordination polymers, [Mn(tda)(bimb)_0.5]_n (1) and [Mn(obb)(bimb)]_n (2) [H₂tda = 2,5- thiophenedicarboxylic acid, H₂obb = 4,4′-oxybis(benzoic acid) and bimb = 1,4-bis(1-imidazol-yl)-2,5-dimethyl benzene], were hydrothermally synthesized by reactions of Mn^II salt with a rigid ligand 1,4-bis(1-imidazol-yl)-2,5-dimethyl benzene and dicarboxylate ligands. Complex 1 exhibits an unusual binodal (3,7)-connected three-dimensional (3D) architecture with point symbol (4⁴.6¹⁷).(6³). Complex 2 is a three-dimensional structure with pcu topology. Furthermore, the luminescent properties of complexes 1 and 2 are investigated. Copyright
