Although the Rh and Ir compounds were found to be diamagnetic with a square-planar geometry, the yet unknown Co complex was predicted to be paramagnetic( E S/T = -22.4 kcal 路 mol-1) with two unpaired electrons localized on the metal center. Three minima were actually located on the ...
Electronic spectral features of the diamagnetic Co(III) and paramagnetic Ni(II) species classify them as six-coordinate distorted octahedral ones. IR spectra (4000–200 cm−1) indicate a monoprotic tridentate (NNS) function of HMPzNBu2 coordinating to the central Co(III) via the pyrazolyl (...
DFT calculations of the parameters of the zfs on a GaIII2CoII model built from the experimental geometry of 2 where the CrIII ion was replaced by a diamagnetic GaIII ion were also carried out, the results of which are summarized in Table 6. A positive local D value (DCo = +5.24 cm...
In com- parison, diamagnetic behavior was seen in a high magnetic field due to the presence of impurity phases, which may be prevented the magnetic domain rotation in the direction of the magnetic field from the low values of the coercive field. The magnetization versus magnetic field shows a...

Namely, a novel low-spin iron(III) porphyrin radical cation, [Fe(TMPÁ)(tBuNC)2]2+, that is diamagnetic. The spectroscopic and magnetic data of this complex will be presented. OCH3 N N Fe N N OCH3 [Fe(TMP)(OCH3)2] S=1 (dxy)2(dxz, dyz)2(a2u)2 H N N N N Fe N N ...
2.1.3. 1H-NMR and 13C-NMR (Hydrogen and Carbon Nuclear Magnetic Resonance) Spectra The 1H-NMR (DMSO-d6) spectra of diamagnetic Zn(II) and Pt(II) complexes showed the disappearance of the signal due to the OH proton indicating the deprotonation of this group. The signal due to the =N...
The sample magnetization data were obtained by the subtraction of background magnetization data for an aluminum foil from the measured data, and then the magnetic susceptibilities were corrected for diamagnetic contributions estimated by Pascal constants [30]. The Mössbauer spectra were recorded on a...
(Co(H2O)6)2+ Identify whether the specified complex is diamagnetic or paramagnetic. If the complex is paramagnetic, further classify it as high spin or low spin and identify the number of unpaired electrons. Rh(en)32+ The cyano-ligand produces a high-spin complex. How ma...
