                                Two new supramolecular transition metal compounds, [Zn(phen)(2)(1,5-NDS)(H2O)] and [Cd(phen)(2)(1,5-NDS)](n) (1,5-NDS = 1,5-naphthalenedisulfonate, phen = 1,10-phenanthroline), were obtained under hydrothermal/solvothermal conditions and structurally characterized by elemental analysis, IR, PXRD, TG-DSC, and single-crystal X-ray determination. They represent the first examples of Zn(II)/Cd(II) supramolecular compounds based on the 1,5-NDS/phen system. The Zn compound exhibits a 3D supramolecular structure via hydrogen bond (O-Ha <-O and C-Ha <-O) and pi-pi interactions. The Cd compound is a 3D supramolecular framework generated by 1D coordinated chains through a hydrogen bond (C-Ha <-O) and pi-pi interactions. In addition, photoluminescence properties for both have been discussed. [Zn(phen)(2)(1,5-NDS)(H2O)] shows an emission peak at 420 nm (lambda (ex) = 342 nm), and [Cd(phen)(2)(1,5-NDS)] (n) displays a strong emission peak at 388 nm with a shoulder peak at 369 nm (lambda (ex) = 332 nm)..
