Abstract
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.
