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—HO hydrogen bonds, weak C—HO hydrogen bonds and C—Hπ 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.

In the title salt, [Zn(C6H15NO3)2](C8H4O4), the ZnII cation, located on a centre of inversion, is coordinated by four O atoms and two N atoms from two tridentate 2-[bis(2-hydroxyethyl)amino]ethanol (BHEA) ligands, giving rise to a slightly distorted octahedral geometry. The terephthalate dianion, located about a centre of inversion, is not coordinated to ZnII but is connected through O—HO contacts with [Zn(BHEA)2]2+ cations, leading to a three-dimensional crystal structure.
