Bis(mu-1,10-phenanthrolin-2-olato-kappa3N,N':O)dicopper(I)(Cu-Cu) monohydrate.

The crystal structure of the title compound, [Cu(2)(C(12)H(7)N(2)O)(2)].H(2)O, shows that this dinuclear complex has shorter Cu-N, Cu-O and Cu-Cu distances within the coordination sphere than similar reported complexes. The complex molecule is located on a centre of symmetry and the water molecule is on a twofold axis of the space group C2/c. The discrete complex molecules are extended into a two-dimensional supramolecular array via pi-pi stacking interactions, intermolecular Cu.Cu interactions and C-H.O hydrogen bonds.
