In the centrosymmetric dinuclear title complex, [Cu2(C5H6O4)2(C12H18N2)2(H2O)2], the CuII atom displays a distorted square-pyramidal coordination environment with the basal plane occupied by two phenanthroline N atoms and two O atoms from different glutarate dianions while a water molecule is located at the apical position. Of the two water H atoms, one is engaged in an intramolecular hydrogen bond with a free oxygen of the dianion whereas the second is engaged in an intermolecular hydrogen bond, building a corrugated layer parallel to (100). These layers are further connected through π–π stacking interactions involving symmetry-related phenanthroline rings [centroid–centroid distance = 3.5599 (17) and 3.5617 (18) Å], building a three dimensionnal network. C—H⋯π interactions involving the phenanthroline ring system are also observed.
