2.1 Preparation of [Co(Me6tren)Cl](ClO4) Analytical grade (Sigma-Aldrich) chemicals were used without further purification. The complex [Co(Me6tren)Cl](ClO4) has been prepared by the published recipe [32] : CoCl2¡¤6H2O (0.200 g, 0.84 mmol) was dissolved in EtOH (20 cm3) at 55 C. Me6tren (0.214 g, 0.92 mmol) dissolved in EtOH (10 cm3) was added dropwise with stirring, forming a blue solution that was stirred overnight at room temperature. NaClO4¡¤4H2O (0.118 g, 0.84 mmol) was added with stirring inducting precipitation of pale blue [Co(Me6tren)Cl](ClO4) (0.237 g, 67%) which was separated by filtration and dried on air. Anal. Calc. for C12H30CoN4O4Cl2: C, 34.11; H, 7.16; N, 13.27. Found: C, 34.36; H, 7.21; N, 13.28%.
