Magnetic susceptibility of compounds

JFiq. X-l.—Curves showing the reciprocal of molar magnetic susceptibility of compounds of cobalt(II) as a function of the absolute temperature. 

For compounds 4-6 where copper (II) ions are bridged by O-P-O groups into a layer, very interesting metamagnetic behaviors are observed. Figure 7 shows the temperature dependent magnetic susceptibilities of compound 4 at 20 kOe, which is characteristic of a ferrimagnetic behavior. The Xm vs T curves measured at 20 kOe, 180 Oe and 30 Oe show a... 

Magnetic susceptibilities of 2-aminothiazole have been measured (139) in order to evaluate the aromatic character of the compound.

Magnetic Susceptibilities. The magnetic susceptibilities of both plutonium compounds (Figure 3) show a weak Curie-Weiss paramagnetism for R, peff=0.87uB, 0=2.6°K9 and for P, Ueff=0.52jj]j,...

A recent report of Hill et al. (192) states that the low values of the magnetic susceptibility of Mn(Et2rftc)2 obtained by Lahiry and Anand are due to partial oxidation of the sample and that the compound has a sextet ground state. The dimeric [Mn(Et2C tc)2]2 is not X-ray isomorphous with Ni(Et2< tc)2, but gives a powder pattern similar to, though not identical with Cu(Et2[Pg.95]

The electrides. Following many experimental difficulties, Dye and coworkers were able to demonstrate that reaction of 18-crown-6 with caesium in a 1 2 ratio (under specified conditions) leads to isolation of shiny, black crystals of a product of composition Cs+(18-crown-6)2 (El-laboudy, Dye Smith, 1983 Dye Ellaboudy, 1984). The solid-state 133Cs nmr spectrum, the esr spectrum, and the magnetic susceptibility of this product all indicated that it was of type Cs+(l8-crown-6).e" that is, a crystalline electride in which the anion is a single electron. In overall terms, this exotic class of compound may be considered to lie on the border between metals and non-metals.
