title: 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.
abstract: In the title coordination polymer, catena-poly[[dichloridomanganese(II)]-μ-1,1-diphenyl-3,3'-[(1R,2R)-cyclohexane-1,2-diylbis(azaniumylylidene)]dibut-1-en-1-olate-κ(2)O:O'], [MnCl2(C26H30N2)]n, synthesized by the reaction of the chiral Schiff base ligand 1,1-diphenyl-3,3'-[(1R,2R)-cyclohexane-1,2-diylbis(azanediyl)]dibut-2-en-1-one (L) with MnCl2·4H2O, 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.
