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-H center dot center dot center dot Cl hydrogen bond between the two Mn-III complexes. In the crystal structure, O-H center dot center dot center dot Cl hydrogen bonds link the molecules into infinite one- dimensional chains along the [100] direction. The crystal structure is stabilized by O-H center dot center dot center dot Cl hydrogen bonds together with weak C-H center dot center dot center dot O and C-H center dot center dot center dot Cl interactions. A C-H center dot center dot center dot pi interaction is also observed in the crystal structure.
