Crystal structure of bis(acetato-κO)diaqua(2,2′-bipyridine-κ2N,N′)manganese(II)

In the title monomeric manganese(II) complex, [Mn(CH3COO)2(C10H8N2)(H2O)2], the metal ion is coordinated by a bidentate 2,2′-bipyridine (bpy) ligand, two water molecules and two axial acetate anions, resulting in a highly distorted octahedral environment. The aqua ligands are stabilized by the forma...

Description
Summary:In the title monomeric manganese(II) complex, [Mn(CH3COO)2(C10H8N2)(H2O)2], the metal ion is coordinated by a bidentate 2,2′-bipyridine (bpy) ligand, two water molecules and two axial acetate anions, resulting in a highly distorted octahedral environment. The aqua ligands are stabilized by the formation of strong intramolecular hydrogen bonds with the uncoordinated acetate O atoms, giving rise to pseudo-bridging arrangement of the terminal acetate groups. In the crystal, the molecules form [010] zigzag chains via O—H...O hydrogen bonds involving the aqua ligands and acetate O atoms. Further, the water and bpy ligands are trans to each other, and are arranged in an off-set fashion showing intermolecular π–π stacking between nearly parallel bipy rings, the centroid–centroid separations being 3.8147 (12) and 3.9305 (13) Å.
