Crystal structure of bis-{μ-4,4'-[1,3-phenyl-enebis(-oxy)]dibenzoato-κ(4) O,O':O'',O'''}bis[(1,10-phenanthroline-κ(2) N,N')zinc(II)] dihydrate.

Two 4,4′-[1,3-phenyl­enebis(­oxy)]dibenzoate anions bridge two 1,10-phenanthroline-chelated ZnII cations about a center of inversion to generate the dinuclear title compound, [Zn2(C20H12O6)2(C12H8N2)2]·2H2O. The geometry about the ZnII atom is a distorted octa­hedron. In the crystal, the mol­ecules are connected by classical O—H⋯O hydrogen bonds, weak C—H⋯O hydrogen bonds and C—H⋯π inter­actions, forming a three dimensional network. π–π stacking is also observed between aromatic rings of adjacent mol­ecules, centroid–centroid distances are 3.753 (2), 3.5429 (16) and 3.5695 (17) A.
