title: Tetra-aqua-(1,10-phenanthroline-κN,N')magnesium(II) bis-[(2,4-dichloro-phen-yl)acetate].
abstract: In the mononuclear title complex, [Mg(C(12)H(8)N(2))(H(2)O)(4)](C(8)H(5)Cl(2)O(2))(2), each Mg(II) ion is hexa-coordinated by two N atoms from a 1,10-phenanthroline ligand [Mg-N = 2.233 (2) Å] and four water mol-ecules [Mg-OW = 2.033 (2) and 2.043 (1) Å] in a distorted octa-hedral geometry. A twofold rotation axis passes through the Mg atom. In the crystal structure, the cations and anions are linked by inter-molecular O-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.804 (2) Å] into layers parallel to the ac plane.
