Özet: Four palladium(II) and platinum(II) complexes of 2,2 '-dipyridylamine (dpya) with saccharinate (sac), cis[Pd(dpya)(sac)(2)]center dot H(2)O (1), cis-[Pt(dpya)(sac)(2)]center dot H(2)O (2), [Pd(dpya)(2)](sac)(2)center dot 2H(2)O (3) and [Pt(dpya)(2)] (sac)(2)center dot 2H(2)O (4), have been synthesized and characterized by elemental analysis, IR, NMR, TG-DTA and X-ray diffraction. In 1 and 2, the metal ions are coordinated by two N-bonded sac ligands, and two nitrogen atoms of dpya, resulting in a neutral square- planar coordination sphere, while in 3 and 4, the metal ions are coordinated by two dpya ligands to generate square-planar cationic species, which are stabilized by two sac counter-ions. The mononuclear species of 1 and 2 interact each other through weak intermolecular N-H center dot center dot center dot O, C-H center dot center dot center dot O and pi center dot center dot center dot pi interactions to form a three-dimensional network, while the ions of 3 and 4 are connected by N-H center dot center dot center dot N and OW-H center dot center dot center dot O hydrogen bonds into one-dimensional chains. On heating at 250 degrees C, the solid cationic complexes of 3 and 4 convert to corresponding anhydrous neutral complexes of 1 and 2 after elimination of a dpya ligand. In addition, all complexes 1-4 are luminescent at room temperature and their emissions seem to be attributed to the MLCT fluorescence.
