Magnetic propertiesSpectroscopyThermal analysisGreen singleヽrystals of the hydroxochromate(III) CaNa[Cr(OH)6] were grown under highly alkaline hydrothermal conditions at about 200 °C. The starting materials Ca(NO3)2·6H2O and Cr(NO3)3·9H2O were reacted in a mixture of water and sodium ...
The performance of a density functional theory approach in calculating the equilibrium bond length, dipole moment, and harmonic vibrational frequency in a series of group 6 (Cr, Mo, W) transition metal-containing diatomic molecules is evaluated. Using flexible basis sets comprised of Slater type fun...
et al. developed the MC simulation and carried out a lot of interesting studies on the MCE of different materials under the external magnetic field such as Mn2PtSn and Mn1.4PtSn [30], LaRO3(R = Mn, Cr and Fe) perovskite [31], (C6H10N2)2[Co(H2O)4P2Mo5O23].6H2O hybrid complex ...
Reaction of (NBzEt3)2[VOCl4] (1a) with NaO2CPh and atmospheric H2O/O2 in MeCN leads to formation of (NBzEt3)2[V5O9Cl(O2CPh)4] 4a; a similar reaction employing (NEt4)2[VOCl4] (1b) gives (NEt4)2[V5O9Cl(O2CPh)4] (4b). Complex 4a·MeCN crystallizes in space group P212121...
Fig. 6. Magnetic structure of La0.3Ca0.7Fe0.7Cr0.3O3-δ at RT. At RT, an average magnetic moment of 1.52(3) μB for Fe and Cr cations was determined, while the calculated magnetic moment would result in μ = (0.7x5μB-0.3x3μB) = 2.5 μB, which is higher than the...
3 ] 3− and [Cu(bpy) 3 ] 2+ ions in the ratio 1:1 [6]. Dimensions of the prepared plate-like single crystals were approximately 2.0 × 0.4 × 0.2 mm 3 up to 3.0 ×0.5 ×0.5 mm 3 . 2 For the EPR measurements, the crystal was mounted on a quartz holder ...

The redox reaction between D-galactonic acid and potassium chromate yields {((lyxonateH(-1)) (galactonateH(-1)) Cr(OH2))K . H2O}(n), with both aldonate molecules acting as bidentate ligands with the carboxylate and one alkoxo function as the donor sites. The shift of the CO2-...
In the present work we have obtained complexes of general formula Cr(L)3, Mn(H2O)2(L)2,Fe(H2O)2(L)2, Fe(L)3, Sn(L)2 and Ag(L); the compounds are microcrystalline or powder-like and with the exception of the tin derivatives, whose limited solubility prohibits conductance ...
