Dark blue microcrystalline powders produced from lithium metal and the cation complexing agent cryptand 2.1.1 C211 were prepared from ammonia and from methylamine solutions. The mole ratio of lithium to cryptand, R, was varied from 0.60 to 2.0 but there was no evidence for Li-. The optical and magnetic properties indicate that LiC211.e- is an electride, a member of the class of materials in which the anions are electrons. Samples were studied by optical transmission spectroscopy, EPR spectroscopy, magnetic susceptibility, and microwave and D.C. conductivities. In many cases several methods were used to characterize samples prepared from the same solution correlation among the various properties is high.
