The compounds were characterized in the solid state by IR, powder XRD, and TGA, and in solution by ³¹P and ¹⁸³W NMR. Alternating current magnetic susceptibility investigations revealed the Ce³⁺ and Yb³⁺ analogues to be single-molecule magnets (SMM), which was further corroborated by sub-kelvin temperature μSQUID studies.
