title: (Butane-1,2,3,4-tetraol-κ(3) O (1),O (2),O (3))(ethanol-κO)tris-(nitrato-κ(2) O,O')holmium(III).
abstract: In the title Ho(III)-erythritol complex, [Ho(NO3)3(C4H10O4)(C2H5OH)], the Ho(III) cation is chelated by a tridentate erythritol ligand and three bidentate nitrate anions. An ethanol mol-ecule further coordinates the Ho(III) cation, completing the irregular O10 coordination geometry. In the crystal, an extensive O-H⋯O hydrogen-bond network links the mol-ecules into a three-dimensional supra-molecular structure.
