Dipyridylmetane dicarboxylic acids with pendant arms containing pyridine groups were prepared. Cu(II) was shown to form square pyramidal complexes with the ligands. Depending on the structure of the pendant arm, the apical position was occupied either by a water molecule or by a pyridyl group from the same molecule or form a neighboring molecule. The reason for the different behavior of the ligands is suggested to be due to stereoelectronically induced conformational preferences of the ligands.
