Abstract: In title compound, [Er(C₁₂H₉O₂)₂(C₁₂H₈N₂)₂(H₂O)₂](C₁₂H₉O₂)·H₂O, the carboxyl groups have only a monodentate coordination mode. The Er^III atom is eight-coordinated in a distorted dodecahedral environment by four O and four N atoms from two 1-naphthaleneacetic acid (NAA) ligands, two aqua ligands and two 1,10-phenanthroline (phen) ligands. A twofold rotation axis passes through Er. The molecules are linked into sheets by O-HO and C-HO hydrogen bonds. There is disorder in the anion and in the solvent water molecule; the site occupancies were set equal to 0.5.
