| Abstract: | The reactions of palladium(II) chloride, PPh3 and heterocyclic-N/NS ligand in a mixture of CH3CN (5 ml) and CH3OH (5 ml) produced PdCl2(PPh3)(L1)]·(CH3CN) (1) (L1 = ADMT = 3-amino-5,6-dimethyl-1,2,4-triazine), PdCl2(PPh3)(L2)] (2) (L2 = 3-CNpy = 3-cyanopyridine), PdCl(PPh3)(L3)]2·(CH3CN) (3), PdCl(PPh3)2(HL3)]Cl (4) (HL3 = Hmbt = 2-mercaptobenzothiazole). The coordination geometry around the Pd atoms in these complexes is a distorted square plane. In 3, L3 acts as a bidentate ligand, bridging two metal centers, while in 4, HL3 appears as monodentate ligand with one nitrogen donor atom uncoordinated. Complexes 1-4 are characterized by IR, luminescence, NMR and single crystal X-ray diffraction analysis. All complexes exhibit luminescence in solid state at room temperature. |
