Abstract
We investigate the effects of disorder in the quasi-one-dimensional me talloporphyrin family of molecule-based magnets. These materials are e lectron transfer salts consisting of linear chains of alternating S=2 Mn-III-porphyrin donors and S=1/2 bridging accepters. Studies of the i rreversibilities, and frequency dependence of the ac magnetic suscepti bility suggest a cluster glass-like behavior in certain compounds at l ow temperatures. The role of the intercalated solvent and its relation to any disorder present in the compounds are discussed.
