Synthesis, Characterization and Molecular structure of bis(2,2′-Bipyridine-N,N′)Bis(Monochloroacetato-O) Manganese(II) Dihydrate

Abstract

[Mn(2-bpy)₂(mcac-O)₂]·2H₂O (2-bpy = 2,2′-bipyridine, mcac = ClCH₂COO⁻) has been synthesized and characterized by elemental and thermal analysis, IR, magnetic and conductivity studies. It crystallizes in space group P2₁/n. The manganese atom adopts a significantly distorted square bipyramidal coordination. Mn–O bonds are distinctly stronger than Mn–N bonds. Molecules of the title compound are linked by strong hydrogen bonds O–H…O(acetate) to form an infinite hydrogen-bonded chain. The hydrogen-bonded chains are assembled via weak C–H…O hydrogen bonds leading to a three-dimensional net structure.
