In the title dinuclear In(III) compound, [In(2)(SO(4))(3)(C(12)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, each In(III) cation is coordinated by a 1,10-phenanthroline (phen) ligand, a water mol-ecule and three sulfate O atoms in a distorted InN(2)O(4) octa-hedral geometry. Three sulfate anions bridge two In(III) cations, forming the dinuclear entities. O-H⋯O and weak C-H⋯O hydrogen bonding is observed in the crystal structure. The crystal structure is further consolidated by π-π stacking between nearly parallel phen ring systems [dihedral angle = 4.2 (4)°], the centroid-centroid distance between benzene rings of adjacent phen ligands being 3.528 (9) Å.
