摘要

In the title coordination polymer, catena-poly[[dichloridomanganese(II)]-mu-1,1-diphenyl-3,3'-[(1R,2R)-cyclohexane-1,2diylbis(azaniumylylidene)]dibut-1-en-1-olate-kappa O-2: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 center dot 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 center dot center dot center dot O- hydrogen bonding and pi-pi interactions between pairs of phenyl rings which strengthen the chains.
