The crystal structure of the title compound, {[NaSm(C_7H_3NO_4)_2(H_2O)_4]·3H_2O}_n, was first reported by van Albada, Gorter & Reedijk [(1999), Polyhedron, 18, 1821-1824]. It has now been reinvestigated and confirmed from single-crystal data, giving greater understanding of the role of the water molecules. The two-dimensional layers found in the compound are built up from six-coordinate NaO_6 polyhedra and nine-coordinate SmN_2O_7 polyhedra. The former share edges with each other along the c axis and the latter are bridged by carboxylate groups of pyridine-2,6-dicarboxylate anions along the b axis. Eight-membered rings of water molecules, connected to one another by hydrogen bonding, are formed in the interlayer spaces.
