Tetra­aqua­bis­(3,5-dinitro­benzoato-[kappa]O1)magnesium tetra­hydrate

G. Smith

Abstract: In the structure of the title compound, [Mg(C7H3N2O6)2(H2O)4]·4H2O, the slightly distorted octa­hedral MgO6 coord­in­ation polyhedron comprises two trans-related carboxyl­ate O-atom donors from mononodentate 3,5-dinitro­benzoate ligands, and four water mol­ecules. The coordinating water mol­ecules and the four water mol­ecules of solvation give both intra- and inter-unit O-H...O hydrogen-bonding inter­actions with carboxyl­ate, water and nitro O-atom acceptors, forming a three-dimensional structure.
