Di-μ-glutarato-κ(4) O (1):O (5)-bis­[aqua­(1,10-phenanthroline-κ(2) N,N′)copper(II)]

In the centrosymmetric dinuclear title complex, [Cu(2)(C(5)H(6)O(4))(2)(C(12)H(18)N(2))(2)(H(2)O)(2)], the Cu(II) 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.
