The synthesis of Mg(2-AEPH)2.8H2O is described and the crystal structure of this compound has been determined by X-ray diffraction methods. The compound is built from octahedral magnesium hexaaqua dications, uncoordinated 2-AEPH- anions and interstitial water molecules. The latter have no metal contacts but are engaged in hydrogen bonding. The packing of the components (]Mg(H2O)6[2+](2-AEPH-)2[).2H2O in the triclinic unit cells (space group P1BAR) appears to be strongly determined by a complicated network of hydrogen bonds, involving all water molecules, the (protonated) amino functions and the O-acceptor sites of the anions.
