Abstract Two pairs of chiral coordination polymers, [Cd2((R)-CBA)2(1,4-BMIB)]n (1-R ), [Cd2((R)-CBA)2(1,4-BMIB)]n (1-S ), {[Cd((R)-CBA)(1,3-BMIB)]·H2O}n (2-R ), and {[Cd((R)-CBA)(1,3-BMIB)]·H2O}n (2-S ) (H2CBA = 4-(1-carboxyethoxy) benzoic acid, 1,4-BMIB = 1,4-bis(2-methyl-1H-imidazol-1-yl)benzene, 1,3-BMIB = 1,3-bis(2-methyl-1H-imidazol-1-yl)benzene), were constructed from lactate derivatives H2CBA and imidazole ancillary ligands under hydrothermal conditions. These complexes show different structures depending on shapes of ancillary ligands. For the linear 1,4-BMIB, complexes 1-R and 1-S are three dimensional (3D) frameworks with dinuclear clusters of Cd(II). For the V-shaped 1,3-BMIB, complexes 2-R and 2-S are two dimensional (2D) layers, where 4-connected Cd(II) centers were isolated by imidazole groups and carboxylic groups from 1,3-BMIB and H2CBA, respectively. The resulting complexes were characterized by PXRD, TGA, UV-visible absorptions and CD measurements. Additionally, 1 and 2 exhibit different photoluminescence behavior in the solid state compared to free H2CBA. Graphical Abstract
