title: 1,5-Bis[(2-meth-oxy-eth-oxy)meth-yl]-1,5-naphthyridine-4,8(1H,5H)-dione.
abstract: The complete mol-ecule of the title compound, C(16)H(22)N(2)O(6), is generated by crystallographic inversion symmetry. The conformation of the N-C-O-C fragment of the side chain is approximately gauche [torsion angle = -74.84 (17)°]. In the crystal, weak C-H⋯O inter-actions link the mol-ecules.
