ABSTRACT
The title Sm(III)-erythritol complex, [Sm(NO3)3(C2H6O)(C4H10O4)], is isotypic with its Nd, Eu, Y, Gd, Tb and Ho analogues. The Sm(III) 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 mol-ecule, completing an irregular coordination sphere. The Sm-O bond lengths range from 2.416â
(2) to 2.611â
(2)â
Å. In the crystal, extensive O-Hâ¯O hydrogen bonding involving all hy-droxy groups and some of the nitrate O atoms links the mol-ecules into a three-dimensional network.
