Abstract

The vibrational (conventional and far-infrared) and diffuse-reflectance spectra in conjunction with magnetic susceptibility measurements over a temperature range down to liquid nitrogen temperature are reported and discussed for the complexes; [Mn(HPOX)2 X 2]; [Mn(HMPX)2 X 2]; [Fe(HPOX)(POX) X 2] and [Fe(HMPX)(MPX) X 2](whereHPOX=pyridine-2-aldoxime (C6H6N2O);POX=C6H5N2O;HMPX=6-Methylpyridine-2-aldoxime (C7H8N2O);MPX=C7H7N2O;X=Cl, Br, I, NO3, NCS, or OA c andX 2=SO4). On the basis of these physical studies a six-coordinated structure is suggested for the manganese(II) and iron(III) complexes.Mössbauer spectra, measured at room-temperature and liquid nitrogen temperature also indicated a six-coordinate geometry for iron(III) complexes.

Zusammenfassung

Es wurden Komplexe von Pyridin-2-aldoxim (HPOX) und 6-Methylpyridin-2-aldoxim (HMPX) vom Typ [Mn(HPOX)2 X 2], [Mn(HMPX)2 X 2], [Fe(HPOX)(POX)X 2] und [Fe(HMPX)(MPX)X 2] (X=Cl, Br, I, NO3, NCS, OA c;X 2=SO4) dargestellt. Die Diskussion erfolgt basierend auf Infrarot-spektroskopie (inklusive fernes IR), Messungen der magnetischen Suszeptibilität (Temp. bis zu fl. N2) undMössbauer-Spektroskopie.
