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-HO hydrogen bonds while inter-complex water O-HN(pyridine) interactions form an infinite chain structure extending along the b axis. The perchlorate anions also function as inter-unit links through water O-HO hydrogen bonds which, together with water O-HO(carbonyl) interactions, give a three-dimensional framework structure.
