In the title compound, [Na(C6H5NH)(C4H10O2)], the Na+ cation is coordinated by the N atoms of two anilide anions, two O atoms of a chelating 1,2-dimethoxyethane (dme) ligand and one O atom of an adjacent dme ligand. The coordination polyhedron around Na+ corresponds to a distorted square pyramid with the N atoms of the anilide groups and the O atoms of the chelating dme unit at the base and a third O atom at the apical position. The anilide anions act as μ-bridging ligands and the 1,2-dimethoxyethane molecules display a μ2-κ3-O,O′ coordination mode. As a result of this connectivity, a polymeric chain structure parallel to  is formed, consisting of Na2O2 and Na2N2 four-membered rings. It should be noted that the remaining H atom of the anilide NH group is not involved in hydrogen bonding.
