Abstract: In the title complex, [La₂(C₁₀H₁₀NO₃)₂(NO₃)₄(C₁₂H₈N₂)₄], each La^III ion is ten-coordinated by four N atoms from two bidentate 1,10-phenanthroline ligands and by six O atoms, two from the N-acetyl-N-phenylglycinate ligands and four from two nitrate anions. Two La^III cations, which exhibit a distorted bicapped square-antiprismatic coordination, are bridged by two N-acetyl-N-phenylglycinate ligands into a dimeric structure, generated by inversion symmetry. There is a - contact between the benzene rings [centroid-centroid distance = 3.409 (3) Å].
