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.
