Abstract: In the title ErIII-erythritol complex, [Er(NO3)3(C2H5OH)(C4H10O4)], the ErIII cation is chelated by one erythritol molecule, three nitrate anions and an ethanol molecule, completing an irregular ErO10 coordination geometry. The Er-O bond lengths are in the range 2.348 (3)-2.583 (3) Å. In the crystal, extensive O-H...O hydrogen bonding links the molecules into a three-dimensional supramolecular structure.
