trans-Tetra­aqua­bis­[bis­(pyridin-3-yl)methanone-κN]manganese(II) bis­(perchlorate)

In the title complex, [Mn(C₁₁H₈N₂O)₂(H₂O)₄](ClO₄)₂, the Mn²⁺ ion is located on an inversion center with the slightly distorted N₂O₄ octa­hedral coordination sphere comprising N-atom donors from two monodentate trans-related bis­(pyridin-3-yl)methanone ligands and four water ligands. The two perchlorate anions are linked to the mononuclear complex mol­ecule through water O—H...O hydrogen bonds while inter-complex water O—H...N(pyridine) inter­actions form an infinite chain structure extending along the b axis. The perchlorate anions also function as inter-unit links through water O—H...O hydrogen bonds which, together with water O—H...O(carbon­yl) inter­actions, give a three-dimensional framework structure.
