(Butane-1,2,3,4-tetraol-κ3O1,O2,O3)(ethanol-κO)tris(nitrato-κ2O,O′)holmium(III)

Abstract

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—H...O hydrogen-bond network links the molecules into a three-dimensional supramolecular structure.
