Abstract

Pentadecanuclear {CII9[W(V)(CN)8]6} clusters were combined with bidentate 2,2'-bipyridine N,N'-dioxide (2,2'-bpdo) ligands resulting in two distinct molecules, {Co9W6(2,2'-bpdo)7} (cluster A) and {Co9W6(2,2'-bpdo)6} (cluster B), capped by seven and six 2,2'-bpdo ligands, respectively. They crystallize within a single {Co9W6(2,2'-bpdo)7}·{Co9W6(2,2'-bpdo)6}·solvent (1) supramolecular network, and reveal single-molecule magnet behaviour with an enhanced energy barrier, a ΔE/kB of 30.0(8) K, which was tentatively ascribed to seven-capped axially deformed cluster A.
