Measurements of the magnetic susceptibility of a powdered sample of VTe in the temperature range 90 - 700 K, and of the a.c. electrical conductivity (σ), thermoelectric power (θ) and dielectric constant (ε′) of pressed pellets of the compound in the temperature range 300 -1100 K are reported. The compound is found to be antiferromagnetic with Neel temperature 420 ± 5 K. The effective paramagnetic moment and paramagnetic Curie temperature are found to be 1.6 μB and - 250 K, respectively. The dependence of σ, θ and ε′ on temperature shows no anomaly at the Neel temperature and is indicative of the metallic nature of the compound.

Two basic halides of molybdenum(111), namely MoOF(H2O)3 and MoOCl(H2O)3 (some samples containing additional loosely bound water), were investigated by absorption spectroscopy in the range 200-50000 cm-1, and by magnetic susceptibility measurements over a temperature range of 100-300 K. Infrared spectra showed bands at about 670 and 1600 cm-l, but not in the range 800-1100 cm-1. Electronic spectra showed poorly defined bands superimposed on strong general absorption. Very weak paramagnetism was observed: this was field dependent. The results are interpreted to show the compounds to be oxygen-bridged polymers [MOX(H2O)3O]n, rather than species containing Mo=O or Mo-0-H groups.

The magnetic properties of the title compound were re-investigated, since a new phase below 240 K has recently been identified. The exchange parameters were evaluated from the temperature dependence of the magnetic susceptibility with a Heisenberg operator taking into account the high pseudo-symmetry of the tetrameric units observed.

(AsPh4)2[Re2FN2Cl7] is prepared by the reaction of ReNCL4 with AsPh4F in acetonitrile solution. The IR spectrum indicates a bridging Re-F-Re complex anion with terminal Re ≡ N ligands. The magnetic susceptibility was measured in the temperature range of 4.8-280 K. The effective magnetic moment is 1.66 B.M. per Re atom (θ = -0.5 K) and corresponds well with Re(VI). The magnetic moment of the well known PPh4[ReNCl4] has also been studied {μeff = 1.67 B.M.; θ = -1.2 K).

Abstract The magnetic susceptibility of distilled lithium has been determined over the temperature range 294 - 3.7 K. The obtained room temperature value of the mass susceptibility is (3.44±0.08)·10-6 cm3 g-1 (cgs units). Below 20 K the susceptibility of the mixture of hexagonal close-packed and body-centered cubic lithium has increased at a rate of about 16%.
