One Mg(II) malonate complex with protonated 2-aminopyridine and hexafluoridophosphate as counterions, (C5H7N2)4[Mg(C3H2O4)2(H2O)2](PF6)2 (1) [C5H7N2 = protonated 2-aminopyridine, C3H4O4 = malonic acid] has been synthesized from purely aqueous media just by mixing the reactants in their stoichiometric proportion and its crystal structure has been determined by single-crystal X-ray diffraction. The role of weak forces like lone pairx3c0; and anionx3c0; interactions in influencing the self-assembly process appears to be of importance. A rare combination of lone pairx3c0; and anionx3c0; interactions in 1, of the type lone pairx3c0;/x3c0;x3c0;/x3c0;anion, is observed, and this unusual supramolecular network is fully described here.
