Halide Complexes

The variation of magnetic susceptibility with temperature for a number of binuclear halide complexes of molybdenum of formula A3IMo2X9 (A = Cs, Et4N, Et3NH; X = Cl, Br) has been studied over the range 90-400�K. The magnetic behaviour is consistent with that expected for magnetically isolated exchange-coupled pairs of molybdenum atoms. The coupling is interpreted as occurring mainly by direct metal-metal interaction rather than superexchange.

Temperature Range

The magnetic susceptibility in the temperature range 80-400 K is reported for copper(II) complexes of the general formula CuLX, where L is benzimidazole substituted in the 2-position by α- or β-hydroxyalkyl groups and in some cases also in the N-position by a methyl group and X is Br-, Cl-, or acetate. The magnetic behaviour of 1-(benzimidazol-2- yl)alkanolato complexes is interpreted in terms of antiferro- magnetically exchange-coupled pairs of copper atoms. The 2- (benzimidazol-2-yl)-alkanolato complex is a linear antiferromagnet.

The Wentzel-Kramers-Brillouin method is used to solve the Schrödinger equation for an electron moving in a uniform magnetic field H , the boundary of the system being a cylinder with its axis lying along the direction of the field. It is found that there are two entirely different types of wave-function possible, one type leading to the small Landau diamagnetism of large systems discussed in part I of this series, the other to the larger diamagnetism of small systems discussed in part IV. Taking into account the occupied states of both types, the steady (non-periodic) contributions to the magnetic susceptibility are derived for all fields in both the low- and high-temperature limits, and for most fields at intermediate temperatures.

Measurements of the temperature dependence (80-380 K) of the magnetic susceptibility of polycrystalline bis(η-cyclopentadienyl)titanium(III) halides [(η-Cp)2- TiX2Ti(η-Cp)2] with X = F, Cl, Br, and I are reported. Characteristic singlet-triplet behaviour is observed with the strength of the Ti-Ti d1-d1 interaction increasing in the sequence F < Cl ≈ I < Br. The position of I ≈ Cl is unexpected and structural data will be required to resolve this anomaly.

Magnetic Phases

The magnetic susceptibility measurements have been made on antiferromagnetic compounds Mn1–xFexSn2 and the magnetic phase diagram was illustrated. The high temperature magnetic phases I and III, major phases, were analyzed on the basis of molecular field theory and explained the change of magnetic structure I⇌III occured at x≈0.8.
