Abstract: The reaction of magnesium(II) chloride tetrahydrate with the proton-transfer compound piperazinediium pyridine-2-carboxylate, (pipzH₂)(pyc)₂ (pipz is pirerazine and pycH is pyridine-2-carboxylic acid) in aqueous solution leads to the formation of the title compound, [Mg(C₆H₄NO₂)₂(H₂O)₂]·0.15H₂O. The Mg atom is six-coordinated in a distorted octahedral environment by two bidentate pyridine-2-carboxylate groups and two O atoms of coordinated water molecules, which are located in cis positions. In the crystal structure, intermolecular O-HO and C-HO hydrogen bonds, and [pi] - [pi] [ [pi] - [pi] distance = 3.5616 (8) Å for pyridine rings; symmetry code: ] and C-H [pi] stacking, connect the various components into a supramolecular structure.
