Cu(CH3COO)2H2O (52 mg, 0,26 mmol) was dissolved in the smallest possible amount of acetone and treated with an excess of Me6TREN. The mixture was left under vigorous stirring for a couple of hours. During this time, the solution turned from blue to green. After evaporation of the solvents, the green product was redisolved in acetone and an excess of KPF6 (dissolved in acetoneas well) was added. The white solid CH3COOK formed on the bottom of the flask and it was filtered off. The light blue solution was dried under vacuum and the solid dissolved in dichloromethanein order to eliminate the excess of KPF6. After filtration of the solid residue, the solution was reduced in volume and the pure product 4 precipitated upon addition of diethylether. Crystals suitable for XRD were grown at low temperature by slow diffusion of diethyl ether into a dichloromethane solution of 4. Yield: 27%; Anal. Calc. for [Cu(L1)(CH3COO)](PF6)2H2O: C, 31.46; H, 6.93; N, 10.49. Found: C, 30.89; H,6.89; N, 10.39%.
