Abstract
Static magnetic susceptibilities have been measured by the Faraday method over the range 1.8-200 K on various solutions of lithium in methylamine. The solutions are diamagnetic; there is an anomaly at the freezing point, with the solid approximately twice as diamagnetic as the liquid. In the concentrated regime, near the "expanded- metal" compound Li(CH3NH2)4, the susceptibility in the liquid is increasingly negative with decreasing temperature; in the solid, it is independent of temperature. The molar susceptibility of Li(CH3NH2)4 is -140 x 10-6. Considerable electron-pairing, favored at lower temperature apparently occurs in this system.
