title: trans-Tetra-aqua-bis-(pyridazine-4-car-box-yl-ato-κO)magnesium(II) dihydrate.
abstract: The crystal structure of the title compound, [Mg(C(5)H(3)N(2)O(2))(2)(H(2)O)(4)]·2H(2)O, is composed of centrosymmetric monomers in which an Mg(II) ion is coordinated by two carboxyl-ate O atoms from the two pyridazine-4-carboxylate ligands. The monomers linked by O-H⋯O and O-H⋯N hydrogen bonds into layers which are held together by hydrogen bonds in which solvent water O atoms act as donors and acceptors, resulting in a three-dimensional network.
