title: Poly[[diaqua-tris-(μ(2)-3-methyl-pyridine-2-carboxyl-ato)(3-methyl-pyridine-2-car-boxyl-ato)sodiumterbium(III)] ethanol monosolvate monohydrate].
abstract: In the title compound, {[NaTb(C(7)H(6)NO(2))(4)(H(2)O)(2)]·C(2)H(5)OH·H(2)O}(n), the Tb(III) atom is eight-coordinated in a slightly distorted square-anti-prismatic geometry defined by four carboxyl-ate O atoms and four pyridine N atoms. The bond lengths lie within the range 2.3000 (2)-2.326 (2) Å for the Tb-O bonds and 2.543 (3)-2.553 (3) Å for the Tb-N bonds. The Na(I) atom is five-coordinated by two water O atoms and three carboxyl-ate O atoms in a distorted square-pyramidal geometry. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
