Abstract

In the title compound, [Na(C(6)H(5)NH)(C(4)H(10)O(2))], the Na(+) cation is coordinated by the N atoms of two anilide anions, two O atoms of a chelating 1,2-dimeth-oxy-ethane (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-dimeth-oxy-ethane mol-ecules display a μ(2)-κ(3)-O,O' coordination mode. As a result of this connectivity, a polymeric chain structure parallel to [100] is formed, consisting of Na(2)O(2) and Na(2)N(2) four-membered rings. It should be noted that the remaining H atom of the anilide NH group is not involved in hydrogen bonding.
