In the title centrosymmetric dinuclear EuIII complex, [Eu2(CH3COO)6(C12H8N2)2], each EuIII cation is coordinated by seven O atoms from five acetate anions and two N atoms from one phenanthroline ligand in a distorted tricapped trigonal-prismatic geometry. Four acetate anions bridge two EuIII cations to form the dinuclear complex, with an Eu⋯Eu distance of 3.9409 (8) Å. Weak intermolecular C—H⋯O hydrogen bonding is present in the crystal structure.
