A fully capped body-centered cubane cluster [Ni-9(btz)(8)-(MeOH)(8){W(CN)(8)}(6)]center dot 18H(2)O center dot 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 W atoms revealed that W1 adopts a distorted dodecahedron, while the other W atoms 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.
