A new oxo-centered, carboxylate bridged trinuclear mixed-valence iron coordination polymer has been obtained under hydrothermal conditions, [(Fe III ) 2 Fe II ( μ 3 -O)(BNA) 6 ] n ( 1 ). Single crystal X-ray diffraction analysis of the black crystal reveals that three iron atoms occupy the vertices of a non-equilateral triangle with the Fe┄Fe distance in the range of 3.245 Å–3.343 Å and are bonded by the μ 3 -oxo-centered and BNA − ligands. The crystal belongs to the monoclinic crystal system with a = 11.2904(6) Å, b = 18.4960(11) Å, c = 21.4349(12) Å, β = 91.029(1), space group P 2 1 / c , GOF = 1.028, final R 1 = 0.0156, w R 2 [ I > 2 σ (I)] = 0.0405.
