Abstract: In the title complex, [Eu(NO₃)₄(C₁₀H₉N₂)(C₁₀H₈N₂)], each Eu^III ion is ten-coordinated by an N atom from a 4,4'-bipyridine molecule, an N atom from a 4'-(4-pyridyl)pyridinium cation and eight O atoms from four different nitrate ions. A C₂ axis passes through the Eu^III ion. Adjacent molecules are connected by strong and weak hydrogen bonds to construct a three-dimensional network.
