catena-Polytetra­aqua­manganese(II)-μ-44′-bipyridine bis­(3-hydroxy­cinnamate) dihydrate

摘要

The title compound, {[Mn(C10H8N2)(H2O)4](C9H7O3)2·2H2O}n, was obtained by the hydro­thermal reaction of manganese chloride with mixed 3-hydroxy­lcinnamic acid (H2 L) and 4,4′-bipyridine (4,4′-bipy) ligands. The structure contains [Mn(C10H8N2)(H2O)₄]²⁺ cations with the Mn^II atoms lying on a centres of inversion and bridged into a linear chain along the a axis by 4,4′-bipy ligands, surrounded by HL ⁻ anions and uncoordinated water mol­ecules. Extensive O—H⋯O hydrogen-bonding and weak π–π inter­actions [centroid–centroid distance = 3.7572  (3) Å] between the constituents lead to the formation of a three-dimensional supra­molecular network.
