metal-organic compounds
The title compound (systematic name: aqua{4,4'-dibromo-2,2'-[1,2-ethanediylbis(nitrilomethylidyne)]diphenolato]chloromanganese(III)), [Mn(C16H12Br2N2O2)Cl(H2O)] or [Mn(Br2salen)Cl(H2O)], was prepared from a methanol solution. The Mn3+ ion displays an elongated octahedral geometry, coordinated by two N and two O atoms from salen, one O atom from the water ligand and one Cl- anion, and is slightly displaced out of the Schiff base N2O2 plane toward the axial Cl- ion. Hydrogen bonds between the coordinated water O and Cl atoms link pairs of molecules into a three-dimensional network.
