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)
1986
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.

The crystal structure of the title compound has been determined from single-crystal x-ray diffraction data. The crystals are tetragonal, space group P42212, withz=2 in a unit cell of dimensionsa=b=9.575(2),c=16.135(5) A. The structure was solved by the usual Patterson and Fourier techniques, and was refined by least-squares analysis to an R value of 0.057 for 545 observed reflexions. Two mepirizole molecules are arranged in a flattened tetrahedral manner (average Cu-N, 1.974 A) around Cu, and coordinated through N atoms. The dihedral angle between N-Cu-N planes of the two ligands is 53.6+°. This geometry seems to result from steric interaction between the ligands. The e.s.r. spectrum is axi…
