In the title compound, [Na(C3H6O)3](n)(I-2)(n), all non-H atoms are in special positions of the space group P6(3)/mcm, with the Na atom in 2b, the I atom in 4c, the carbonyl O atom and the C atom attached to it both in 6g, and the methyl C atom in 12k. The H atoms of the rotationally disordered methyl groups are in 24l general positions but with occupancies of 0.5, because they occur in two sets related by a crystallographic mirror plane. Infinite chains are created by face-sharing octahedral Na-coordination polyhedra, with Na-O and Na...Na distances of 2.439 (5) and 3.2237 (4) Angstrom, respectively. I atoms form infinite linear chains, in which the I-atom separation is 3.2237 (4) Angstrom.
