Abstract

Two new cyclopalladated complexes with 2-(5-methyl-3-phenyl-1H-pyrazol-1- yl)ethanol (HL1) ligand: [PdCl(L1)(HL1)] (1) and [Pd(NO3)(L1)(HL1)] (2) were prepared and fully characterized by elemental analyses, conductivity measurements, mass spectrometry, IR and NMR spectroscopies. In complexes 1 and 2, one of the ligands is bidentately coordinated to the Pd atom through the Npz atom and the Cph atom (L1), and the other ligand only presents monodentately coordination to the Npz atom (HL1). The metallic atom completes the coordination with a Cl- (1) or NO 3- (2) anion in monodentate form, respectively. This synthetic approach represents an easy and convenient method for the design of attractive cyclopalladated complexes. © 2014 Elsevier B.V.
