Di-μ-glutarato-κ4O1:O5-bis­[aqua­(1,10-phenanthroline-κ2N,N′)copper(II)]

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) A], building a three dimensionnal network. C—H⋯π inter­actions involving the phenanthroline ring system are also observed.
