摘要：
Three tungsten oxychloride clusters containing the nearly D-3d symmetric [((W6O6Cl6i)-Cl-i)Cl-6(a)](n-) (n = 2, 3) core were prepared from the cluster acid (H5O2)(2)[W6O6Cl12]4H(2)O and structurally characterized by single-crystal X-ray diffraction. The copper compound [Cu(H2O)(4)][W6O6Cl12]12H(2)O releases water molecules to yield [Cu(H2O)(6)][W6O6Cl12]. Both compounds are represented as diamagnetic clusters, having 14 electrons in W-W bonding states. Magnetic measurements on the calcium compound [Ca(H2O)(7)](2)[W6O6Cl12]Cl revealed a paramagnetic cluster having 15 valence electrons.
