Abstract:

3-(1,1,1-Tri-methyl-hydrazin-1-ium-2-yl)propano-ate (C6H14N2O2, 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-di-aqua-bis-[3-(1,1,1-tri-methyl-hydrazin-1-ium-2-yl)propano-ate]disodium] dibromide tetra-hydrate], [Na2(C6H14N2O2)2(H2O)6]Br2·4H2O, and poly[[di-μ-aqua-di-aqua-[μ-3-(1,1,1-tri-methyl-hydrazin-1-ium-2-yl)propano-ate]disodium] diiodide], [Na2(C6H14N2O2)2(H2O)4]I2. The coordination numbers of the sodium ions are 6; the coordination polyhedra can be described as distorted octa-hedra. Metal ions and M zwitterions are assembled into infinite layers via electrostatic inter-actions and hydrogen-bonded networks. These layers are connected via electrostatic attraction between halogenide ions and positive tri-methyl-hydrazinium groups into a three-dimensional structure.
