Summary
Some copper(II) complexes of the types: Cu(HPPK)-(PPK)X, Cu(HMPK)(MPK)X (where HPPK = syn-phenyl-2-pyridylketoxime, HMPK = syn-methyl-2-pyridylketoxime and X = Cl−, Br−, I−, NO3 −, SCN− or SeCN−) Cu(HPPK)2SO4 3 H2O and Cu(HMPK)2SO4 · 3 H2O were synthesized and characterized by analysis, magnetic susceptibility, e.s.r., reflectance and i.r. spectral measurements. The spectral data suggest that Cu(HPPK)(PPK)X and Cu(HMPK)(MPK)X containcis square-coplanar [Cu(HPPK)(PPK)]+ and [Cu(HMPK)(MPK)]+ units respectively, linked by weakly coordinated anions, giving infinite polymeric highly distorted octahedral chain structures, whereas Cu(HPPK)2SO4 · 3H2O and Cu(HMPK)2SO4 · 3 H2O have acis distorted octahedral structure containing two ligand molecules of ketoxime and a bidentate sulphate group. The polycrystalline e.s.r. spectra suggest a distorted octahedral stereochemistry for the CuII ion involving a\(d_{x^2 - y^2 } \) ground-state. By using e.s.r. and reflectance spectral data, the orbital reduction parameters, k11 and k1 were calculated and interpreted in terms of molecular orbital coefficients.
