Single-molecule magnet behaviour in polynuclear assembly of trivalent cerium ions with polyoxomolybdates

摘要

An isopolyoxomolybdate-based POM is coordinated to trivalent cerium ions to afford a hybrid complex namely, Ce(dmso)(8) Ce(eta(2)-NO3)(2)(dmso)(4)(alpha-Mo8O26)(0.5)Mo6O19. The original electrostatic environment created around the Ce-III by its coordination to the isopolyoxomolybdate core induces complex single-molecule magnet behavior.
