A one-dimensional coordination polymer formed from the reaction of 1,1-diphenyl-3,3′-[(1R,2R)-cyclo­hexane-1,2-diylbis(aza­nedi­yl)]dibut-2-en-1-one with MnCl₂·4H₂O

A one-dimensional chiral helical coordination polymer was synthesized from the rigid chiral bidentate Schiff base ligand 1,1-diphenyl-3,3′-[(1R,2R)-cyclo­hexane-1,2-diylbis(aza­nedi­yl)]dibut-2-en-1-one with Mn^II. The structure displays intra­molecular ionic N⁺—H...O⁻ hydrogen bonding and π–π inter­actions between pairs of phenyl rings which strengthen the chains.
