Two metal compounds, $[Co(phen)_2(H_2O)_2]{cdot}2H_2SIP{cdot}2H_2O$ 1 and $[Ni(phen)_3]{cdot}2H_2SIP{cdot}3H_2O$ 2, have been obtained by incorporating 1,10-phenanthroline (phen) and 5-sulfoisophthalic acid monosodium salt ($NaH_2SIP$) ligands under hydrothermal conditions. Meanwhile, the two compounds were characterized by element analysis, IR, XRD, TG-DTA and single-crystal X-ray diffraction. Both 1 and 2 present 3D supramolecular structures via O-H${cdots}$O hydrogen bond interactions. Luminescent properties for 1 and 2 were also studied. The compound 1 has two fluorescence emission peaks centered at 398 nm attributed to the intraligand emission from the SIP ligand and at 438 nm assigned to the combined interaction of intraligand ${pi}^*-{pi}$ transitions of the phen ligand and ligand-to-metal-charge-transfer (LMCT) transitions (${lambda}_{ex}$ = 233 nm). The compound 2 shows one emission band centered at 423 nm with a shoulder peak at 434 nm which may be originated from the intraligand ${pi}^*-{pi}$ transitions of the phen ligand (${lambda}_{ex}$ = 266 nm).
