In the title coordination polymer, catena ‐poly[[dichloridomanganese(II)]‐μ‐1,1‐diphenyl‐3,3′‐[(1 R ,2 R )‐cyclohexane‐1,2‐diylbis(azaniumylylidene)]dibut‐1‐en‐1‐olate‐κ 2 O : O ′], [MnCl 2 (C 26 H 30 N 2 )] n , synthesized by the reaction of the chiral Schiff base ligand 1,1‐diphenyl‐3,3′‐[(1 R ,2 R )‐cyclohexane‐1,2‐diylbis(azanediyl)]dibut‐2‐en‐1‐one ( L ) with MnCl 2 ·4H 2 O, the asymmetric unit contains one crystallographically unique Mn II ion, one unique spacer ligand, L , and two chloride ions. Each Mn II ion is four‐coordinated in a distorted tetrahedral coordination environment by two O atoms from two L ligands and by two chloride ligands. The Mn II ions are bridged by L ligands to form a one‐dimensional chain structure along the a axis. The chloride ligands are monodentate (terminal). The ligand is in the zwitterionic enol form and displays intramolecular ionic N + —H...O − hydrogen bonding and π–π interactions between pairs of phenyl rings which strengthen the chains.
