Sumario:3-(1,1,1-Tri­methyl­hydrazin-1-ium-2-yl)propano­ate (C(6)H(14)N(2)O(2), M, more commonly known under its commercial names Meldonium or Mildronate) co-crystalizes with sodium bromide and sodium iodide forming polymeric hydrates poly[[tetra-μ-aqua-di­aqua­bis­[3-(1,1,1-tri­methyl­hydrazin-1-ium-2-yl)propano­ate]disodium] dibromide tetra­hydrate], [Na(2)(C(6)H(14)N(2)O(2))(2)(H(2)O)(6)]Br(2)·4H(2)O, and poly[[di-μ-aqua-di­aqua­[μ-3-(1,1,1-tri­methyl­hydrazin-1-ium-2-yl)propano­ate]disodium] diiodide], [Na(2)(C(6)H(14)N(2)O(2))(2)(H(2)O)(4)]I(2). The coordination numbers of the sodium ions are 6; the coordination polyhedra can be described as distorted octa­hedra. Metal ions and M zwitterions are assembled into infinite layers via electrostatic inter­actions and hydrogen-bonded networks. These layers are connected via electrostatic attraction between halogenide ions and positive tri­methyl­hydrazinium groups into a three-dimensional structure.
