Transition Metal Chemistry of Oxime Containing Ligands. Part XXIV. Complexes of Manganese(II) and Cobalt(II) with Quinoline-2-aldoxime and Isoquinoline-3-aldoxime

Abstract

Complexes of the types [M(HL)₂(X)₂] (where M = Mn(II) or Co(II), HL = quinoline-2-aldoxime (Hqox) or isoquinoline-3-aldoxime (Hiqox) and X = Cl⁻, Br⁻, I⁻, NCS⁻, NCSe⁻, OAc⁻, or 1/2 SO₄ ⁻) and [M(HL)₂(NO₃)](NO₃), (where M = Mn(II) or Co(II); and HL = Hqox or Hiqox) have been synthesized and characterized on the basis of elemental analysis, molar conductance, molecular weight determinotion, X-ray powder diffraction, variable temperature magnetic susceptibility, reflectance and IR spectral data. These studies suggest a dimeric halo-bridged cis distorted octahedral structure for[M(HL)₂(X)₂] (where M = Mn(II) or Co(II), HL = Hqox or Hiqox and X = Cl⁻, Br⁻ or I⁻) complexes and a monomeric cis-pseudo octahedral structure for the remaining complexes.
