Abstract

A fully capped body-centered cubane cluster [Ni₉(btz) ₈-(MeOH)₈{W(CN)₈}₆]·18H ₂O·6MeOH (1) [btz = 2,2′-bi(4,5-dihydrothiazine)], whose periphery was modified with sulfur-containing bidentate ligands acting as potential anchoring sites to electrodes and substrates, was prepared. The geometric analyses around the Watoms revealed that W1 adopts a distorted dodecahedron, while the other Watoms are closer to a square-antiprism geometry than a dodecahedron. The magnetic studies of 1 reveal that ferromagnetic couplings are operative through CN bridges, generating an S = 12 ground state. It appears that magnetic anisotropy of a molecule is venerable to subtle structural variations.
