Aqua(2,9-dimethyl-1,10-phenanthroline-κ2N,N′)bis(3-hydroxybenzoato-κO)manganese(II)–2,9-dimethyl-1,10-phenanthroline–water (1/1/1)

Abstract

In the title compound, [Mn(C7H5O3)2(C14H12N2)(H2O)]·C14H12N2·H2O, the MnII ion is coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand, two monodentate 3-hydroxybenzoate anions (3-HBA) and one water molecule in a distorted trigonal-bipyramidal environment. An uncoordinated dmphen and an uncoordinated water molecule cocrystallized with each complex molecule. Intra- and intermolecular O—H...N and O—H...O hydrogen bonds are also present between the coordinated 3-HBA and water molecules and the uncoordinated dmphen and water molecules in the crystal. The packing of the structure is further stabilized by π–π stacking interactions involving dmphen molecules, with a centroid–centroid separation of 3.705 (3) Å.
