Abstract

Two new hexanuclear octahedral cyanido-bridged clusters, {[Cd^II(bpy)₂]₄[W^IV(CN)₈]₂}·10H₂O (Cd₄W₂) and {[Cd^II(bpy)₂]₄[Mo^IV(CN)₈]₂}·10H₂O (Cd₄Mo₂), have been obtained and characterized structurally and photomagnetically. Both compounds show a very rare and reversible single-crystal-to-single-crystal transformation upon dehydration accompanied by marked color changes in the case of Cd₄W₂. Moreover, irradiation of Cd₄Mo₂ using 436 nm light induces a reversible photomagnetic effect due to the LIESST-like singlet-triplet transition at the Mo^IV center. Analogous photomagnetic experiments for Cd₄W₂ did not lead to any significant change of its magnetic moment.
