Bottom Line: In the title coordination polymer, {[Nd(C(5)H(2)N(3)O(6))(C(2)O(4))(H(2)O)(4)]·4H(2)O}(n), the oxalate dianions link adjacent nine-coordinate, tricapped trigonal-prismatic Nd(III) atoms into a chain running along the b axis.The 3,5-dinitropyridin-4-oxido N-oxide ligand is formally a zwitterionic anion; the anion binds to the metal atom through the N-oxide O atom.The chains are connected into a three-dimensional network by O-H⋯O hydrogen bonds involving the coordinated and uncoordinated water mol-ecules.

ABSTRACT
In the title coordination polymer, {[Nd(C(5)H(2)N(3)O(6))(C(2)O(4))(H(2)O)(4)]·4H(2)O}(n), the oxalate dianions link adjacent nine-coordinate, tricapped trigonal-prismatic Nd(III) atoms into a chain running along the b axis. The 3,5-dinitropyridin-4-oxido N-oxide ligand is formally a zwitterionic anion; the anion binds to the metal atom through the N-oxide O atom. The chains are connected into a three-dimensional network by O-H⋯O hydrogen bonds involving the coordinated and uncoordinated water mol-ecules.

Thermal ellipsoid plot (Barbour, 2001) of a portion of the chain motif of [Nd(H2O)4(C5H2N3O6)(C2O4).H2O]n at the 50% probability level; hydrogen atoms are shown as spheres of arbitrary radius. Symmetry codes: i = 1 - x, 1 - y, 1 - z; ii = 1 - y, 2 - y, 1 - z.
