Oxidation of Mn(II) in aqueous solution by ammonium ceric nitrate in the presence of acetylacetone (acacH) followed by subsequent crystallization from methanol leads to [Mn(acac)2(HOCH3)2]3[Ce(NO3)6] (1). The icosahedrally coordinated Ce(NO3)63− ion with six octahedrally disposed hydrogen bond acceptor sites links the cations into a hydrogen bonded α-polonium-like network with a 2-fold parallel interpenetration.
