【 摘 要 】

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) Å.
