摘要
In the title compound, [Mg(C 8 H 6 NO 4 ) 2 (H 2 O) 2 ] n , the Mg II ion lies on a twofold roatation axis and is coordinated in a slightly distorted octa-hedral environment. Pairs of bridging ammonium-isophthalate ligands connect symmetry-related Mg II ions, forming chains along [010]. In the crystal, inter-molecular O - H⋯O and N - H⋯O hydrogen bonds link these chains into a three-dimensional network. The centroids of pairs of symmetry-related benzene rings within a chain are separated by 3.5707 (12) Å.
