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

B. Liu and F. Zhang

Abstract: 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.
