Magnetic susceptibility of Co4+(d5) in octahedral and tetrahedral environments
Journal of Solid State Chemistry, 1973 Abstract Measurements of magnetic susceptibility on compounds containing stoichiometric Co4+ are reported. The compound Ba2CoO4 has the Co4+(d5) ion at a tetrahedral site and displays a susceptibility of the expected magnitude for S = 5 2 .

Magnetic susceptibilities of trivalent lanthanide ions in an octahedral environment
The Journal of Chemical Physics, 1974 Magnetic susceptibilities for eight lanthanide ions in Cs2NaLnCl6 were measured from 2.5 to [inverted lazy s] 80°K with a vibrating sample magnetometer. Computer fitting of the data for Cs2NaCeCl6 gave g = 1.43 for the Γ7 ground level, and f2 = 3.85 for the Γ8 excited level.

Magnetic Susceptibility of Yb3+ in an Octahedral Environment
The Journal of Chemical Physics, 1971 The magnetic susceptibility of Yb3+ in Cs2NaYbCl6 was measured from 2.5 to 100°K and showed Curie–Weiss temperature dependence from 2.5 to 20°K (μeff = 2.46 μB, θ = 0.95°C) and from 45 to 100°K (μeff = 4.47 μB, θ = 70°C), with a transitional region from 20–45°K.

Monatshefte für Chemie - Chemical Monthly, 1985 Amorphous aluminosilicates containing up to 5.8 wt.% chromium have been prepared by cation exchange on an amorphous sodium aluminosilicate using Cr(III) salts. Electronic spectroscopy has shown that the ligand arrangement around the Cr(III) sites does not correspond to the octahedral geometry.

European Journal of Inorganic Chemistry, 2000 GeI2 reacts with [M2(CO)10]2– (M = Cr, W) leading to reductive coupling of two GeI2 units to produce the [Ge2I4]2– ligands of [{(OC)5M}I2Ge–GeI2{M(CO)5}]2– (1a and 2a). The [Ph4P] salts of these anions have been characterised by X-ray structure analyses as have the [Ph4P] salts of [{(OC)5M}Cl2Ge–GeCl2{M(CO)5}]2– (1b and 2b) obtained from the iodo ...

High magnetic fields study of asymmetric Co(II) dimer in octahedral ligand environment
Solid State Communications, 2003 Abstract Magnetic properties of the dinuclear cobalt complex [Co2(ox)tpmc](ClO4)2·3H2O have been studied from the magnetization data obtained in the high magnetic field-low temperature experiment ( B≤20 T , T=4.2 K ). An excellent agreement between experimental and calculated data was achieved within the framework of the isolated ...

The Journal of Physical Chemistry A, 2011 Electronic spectra of 3d(n) transition ions in an octahedral ligand surrounding have been studied using the modified crystal field approach (MCFA), which includes a relativistic spin-orbital interaction. A new variable parameter, the effective nuclear charge Z(eff) of a metal ion that allows accounting implicitly the covalence degree of a metal-ligand ...
