The magnetic susceptibility, measured with a vibrating sample magnetometer (Foner), calibrated with nickel (purity 99.99% — specific susceptibility at 293°K 55 cgs/g) at 293 0.2°K with a magnetic field of 17,700 G, is 101.39 0.20 10"6 cgs/g. This value may be compared with 101.65 0.20 10 6 cgs/g for manganese diphosphate prepared by thermal decomposition of the ammonium manganese phosphate. The value calculated from Reference 7 is 101.96 0.20 cgs/g. 

From the changes in magnetic susceptibility of nickel—silica catalysts during ethylene adsorption at room temperature, Selwood [55] has concluded that ethylene exists both as an associatively and a dissociatively adsorbed species. On increasing the temperature, the dissociative adsorption becomes more important. Thus at 100° C, the susceptibility changes are consistent with the formation of six bonds to the surface for each adsorbed ethylene molecule, suggesting the following process... 

The theory of the magnetic susceptibility of nickel(II) complexes is well established and several review articles have already appeared.375-379 A quantity of interest in studying the magnetic properties of nickel(II) complexes is the effective magnetic moment p = (8xT). 

Ginsberg et al.2917 made a detailed analysis of the average magnetic susceptibility of nickel(II) dimers and fitted the temperature dependence of the magnetic susceptibility of [Ni2(en)4X2]Y2 (X, Y = Cl, Br X = NCS, Y = I). The model Hamiltonian they used is... 

Exchange interactions in heterodinuclear transition metal complexes have attracted the attention of many researchers in the last few years. Nickel(II)-copper(II) dimers are, in a sense, the simplest systems to be investigated and several complexes containing paramagnetic nickel(II) and copper(II) ions have been reported, as pure complexes2985-2987 or as impurities in a parent lattice.2959,2987"2991 Magnetic susceptibility or EPR spectroscopy has been used to... 

Nickel(IV) complexes have a d6 electronic configuration and are always diamagnetic or weakly paramagnetic with a temperature-independent magnetic susceptibility. The characterization of these complexes is generally based on the stoichiometry and the electrochemical behaviour. 

Complexes related to CoHg(SCN)4, the well-known calibrant used in magnetic susceptibility measurements, have recently been prepared containing silver(I).146,147a In the presence of a number of Lewis bases octahedral adducts such as Co[Ag(SCN)2] -2DMF were obtained. Magnetic moments indicated the presence of high-spin cobalt(II). With nickel(II), two types of complex...
