Abstract: The asymmetric unit of the title complex, [Mn(C₂₈H₃₀N₂O₂)Cl(H₂O)][Mn(C₂₈H₃₀N₂O₂)Cl(CH₃OH)], contains two discrete Mn^III complexes of a Schiff base ligand, with an N₂O₂ donor set. Both Mn^III centers are in a distorted octahedral geometry with the N₂O₂ donor atoms of the tetradentate Schiff base dianion in the equatorial plane. The axial positions in the coordination environment of one Mn^III complex are occupied by a chloride ion and a water molecule, but a methanol molecule replaces the water molecule in the other complex. The coordinated water molecule takes part in an O-HCl hydrogen bond between the two Mn^III complexes. In the crystal structure, O-HCl hydrogen bonds link the molecules into infinite one-dimensional chains along the [100] direction. The crystal structure is stabilized by O-HCl hydrogen bonds together with weak C-HO and C-HCl interactions. A C-H interaction is also observed in the crystal structure.
