Abstract

New palladium(II) and platinum(II) complexes, cis-[Pd(bpy)(sac)(2)] (1) and cis-[Pt(bpy)(sac)(2)] (2), where sac = saccharinate, bpy = 2,2'-bipyridine, have been synthesized and characterized by elemental analysis, UV-Vis, IR, H-1 NMR and C-13 NMR. The structures of the DMSO solvated complexes are determined by X-ray diffraction. Both complexes are isomorphous and the metal ions are coordinated by two N-bonded sac ligands, and two nitrogen atoms of pyridyl groups of bpy in a cis fashion. The mononuclear species interact each other through weak intermolecular C-H center dot center dot center dot O hydrogen bonds, C-H center dot center dot center dot pi and pi-pi interactions leading to three-dimensional supramolecular networks. All complexes exhibit a high thermal stability in the solid state, and are fluorescent in the solution.
