(Top) The structure of the asymmetric unit of Mg-HM (yellow coloured water molecules were symmetry generated). The hydrogen bond formed in the asymmetric unit is shown as a black dashed line. The five positions where the second maleate anion can be placed are indicated by bold Roman numbers I to V. (Bottom) MADs of the five O—H bond lengths obtained from B3LYPmol (blue bars) and B3LYPIChE (red bars) when the second maleate anion is placed in each different position I to V.
