A fully capped bodycentered cubane cluster [Ni9btz8MeOH8{WCN8}6]·18H2O·6MeOH 1 [btz = 2,2′bi4,5dihydrothiazine], whose periphery was modified with sulfurcontaining 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 squareantiprism geometry than a dodecahedron. The magnetic studies of 1reveal 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. © WileyVCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008 |
