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

Abstract

An isopolyoxomolybdate-based POM is coordinated to trivalent cerium ions to afford a hybrid complex namely, [Ce(dmso) 8 ][Ce(η 2 -NO 3) 2 (dmso) 4 (α-Mo 8 O 26) 0.5 ][Mo 6 O 19 ]. The original electrostatic environment created around the Ce III by its coordination to the isopolyoxomolybdate core induces complex single-molecule magnet behavior.
