Diaqua[N, N′-bis(salicylidene) propanediamine(2-)] manganese(III) chloride

The title compound (systematic name: diaqua{2,2 '-[propane1,3-diylbis(nitrilomethylidyne)]diphenolato} manganese(III) chloride), [Mn(C17H16N2O2)(H2O)(2)]Cl, consists of an Mn III cation complex and a counter-anion. In the complex, the Mn3+ ion is six-coordinated by the dianion of the tetradentate ligand N,N '-bis(salicylidene)-1,3-diaminopropane and two water molecules in a distorted octahedral geometry. The molecules are assembled through intermolecular O-H center dot center dot center dot Cl and O - H center dot center dot center dot O hydrogen bonds and pi - pi interactions [ the centroid centroid distance is 3.865 angstrom and the dihedral angle between the ring planes is 12.9 degrees] along the a axis.
