Three tungsten oxychloride clusters containing the nearly D 3 d symmetric [(W 6 O 6 i Cl 6 i )Cl 6 a ] n – ( n = 2, 3) core were prepared from the cluster acid (H 5 O 2 ) 2 [W 6 O 6 Cl 12 ] · 4H 2 O and structurally characterized by single‐crystal X‐ray diffraction. The copper compound [Cu(H 2 O) 4 ][W 6 O 6 Cl 12 ] · 12H 2 O releases water molecules to yield [Cu(H 2 O) 6 ][W 6 O 6 Cl 12 ]. Both compounds are represented as diamagnetic clusters, having 14 electrons in W–W bonding states. Magnetic measurements on the calcium compound [Ca(H 2 O) 7 ] 2 [W 6 O 6 Cl 12 ]Cl revealed a paramagnetic cluster having 15 valence electrons.
