Study of the coordination behaviour of (3,5-diphenyl-1H-pyrazol-1-yl)ethanol against Pd(II), Zn(II) and Cu(II)

► The coordination behaviour of N-pyrazole ligands was studied for its application in catalyst, magnetic properties and others. ► One of the our research lines is the synthesis and characterization on N-pyrazole 1,3,5-trisubstituted. ► Pd(II), Zn(II) and Cu(II) complexes with N,O-hybrid ligands are described. ► The Magnetic Susceptibility and EPR for complex of Cu(II) are presented.
