Iron(iii) and titanium(iv) oxoalkoxide chemistry: synthetic, structural, magnetochemical and spectroscopic studies of [Ti3(μ3-OPri)2(μ-OPri)3(OPri)6][FeCl4] and [Fe5(μ5-O)(μ-OPri)8Cl5]

“…As for C, the unusually low room-temperature effective magnetic moment determined by a modified Gouy method 27 in toluene solution (m eff ¼ 3.97 m b per iron) suggests an intermediate spin state (S ¼ 3/2) for the metal centres. The S ¼ 3/2 state is the less common spin state for a d 5 ion; it can be obtained in low symmetry ligand fields and has been well characterised in a number of square-pyramidal mononuclear dithiocarbamates and macrocyclic iron(III) systems.…”

The first thermochromic vanadium(IV) alkoxide system

“…Since oxo groups in vanadium(IV) compounds form very easily if traces of air or water are present, the successful preparation of this vanadium(IV) alkoxide is a confirmation of an adequate preparative technique and suitable experimental conditions. Room temperature magnetic susceptibility measurements on I were carried out by a modified Gouy method [11] in the solid state and gave an effective magnetic moment of 1.74 l b per metal atom, very close to the spinonly value for d 1 vanadium(IV) centres.…”

“Particle-Free” Magnetic Actuation of Droplets on Superhydrophobic Surfaces Using Dissolved Paramagnetic Salts

“…Magnetic susceptibility of the salt solutions at various concentrations was obtained using eq : where χ w is mass magnetic susceptibility of water (−0.72 × 10 –6 cm 3 g 1 ), m s is the mass of salt, and m w is the mass of water …”

“…where χ w is mass magnetic susceptibility of water (−0.72 × 10 −6 cm 3 g 1 ), m s is the mass of salt, and m w is the mass of water. 30 Table 1 gives a summary of important properties of the salts used.…”
