The first example for μ-aqua-μ-oxo bridging of two transition-metal centers is the cation of 2. This compound is formed as green crystals from CuCl2·2H2O and L in methanol after addition of aqueous NaClO4 solution. 2 is ferromagnetic. 1, the cation of which belongs to a frequently encountered type, is formed as blue crystals from Cu(ClO4)2·6H2O and L in water. 1 is antiferromagnetic. Surprisingly, in the crystal the two tautomers have the same space group and very similar structures.
