Hexafluorophosphate and Oxalate Complexes of 4-Methoxy-2-(5-methoxy-3-methyl-pyrazol-1-yl)-6-methylpyrimidine with Co(II), Ni(II), and Cu(II)

Abstract

Complexes of Co(II), Ni(II) and Cu(II) with the title ligand, L, have been prepared and characterized through elemental analysis, conductance measurements, electronic and infrared spectra, and magnetic measurements. For all hexafluorophosphate complexes monomeric species with CuL₂ ²⁺ and ML₃ ²⁺ (M=Co,Ni,Cu) have been isolated. In the oxalate complexes the C₂O₄ ⁼ group act as a bidentate bridge to form compounds with probable dimeric (copper(II)) or polymeric (cobalt(II) and nickel(II)) structures.
