In the title HoIII–erythritol complex, [Ho(NO3)3(C4H10O4)(C2H5OH)], the HoIII cation is chelated by a tridentate erythritol ligand and three bidentate nitrate anions. An ethanol molecule further coordinates the HoIII cation, completing the irregular O10 coordination geometry. In the crystal, an extensive O—HO hydrogen-bond network links the molecules into a three-dimensional supramolecular structure.

The title SmIII–erythritol complex, [Sm(NO3)3(C2H6O)(C4H10O4)], is isotypic with its Nd, Eu, Y, Gd, Tb and Ho analogues. The SmIII cation exhibits a coordination number of ten and is chelated by a tridentate erythritol ligand and three bidentate nitrate anions. It is additionally coordinated by an O atom of an ethanol molecule, completing an irregular coordination sphere. The Sm—O bond lengths range from 2.416 (2) to 2.611 (2) Å. In the crystal, extensive O—HO hydrogen bonding involving all hydroxy groups and some of the nitrate O atoms links the molecules into a three-dimensional network.
