Abstract

In the title centrosymmetric Mg(II) complex, [Mg(2)(C(7)H(3)NO(4))(2)(H(2)O)(6)], each Mg cation is N,O-chelated by a pyridine-2,4-dicarboxyl-ate dianion and is coordinated by three water mol-ecules. A carboxyl-ate O atom from the neighboring pyridine-2,4-dicarboxyl-ate dianion bridges the Mg cation to complete the MgNO(5) distorted octa-hedral coordination geometry. The dinuclear complex mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonding, forming a three-dimensional supra-molecular structure.
