    Snippet: All commercially available reagents and chemicals were of analytical-or reagent-grade purity and used as received. The chemical elemental analysis for the determination of C, H, N was done on a Carlo-Erba LA-118 microdosimeter (Lakewood, CA, USA). 1 H-NMR and 13 C-NMR spectra were recorded at room temperature on a Bruker DRX 400 spectrometer (Billerica, MA, USA) in DMSO-d6, using TMS as the internal standard.

    Document: All commercially available reagents and chemicals were of analytical-or reagent-grade purity and used as received. The chemical elemental analysis for the determination of C, H, N was done on a Carlo-Erba LA-118 microdosimeter (Lakewood, CA, USA). 1 H-NMR and 13 C-NMR spectra were recorded at room temperature on a Bruker DRX 400 spectrometer (Billerica, MA, USA) in DMSO-d6, using TMS as the internal standard. IR spectra were recorded on a Specord-M80 spectrophotometer (Leipzig, Germany) in the 4000-400 cm −1 region using KBr pellets. The complexes were studied by thermogravimetry (TG) in a static air atmosphere, with a sample heating rate of 10 °C/min using a STA 6000 Perkin Elmer (Waltham, MA, USA). Electronic spectra were recorded using the JascoV-670 spectrophotometer (Tokyo, Japan) in diffuse reflectance, using MgO dilution matrices. EPR spectra were recorded on polycrystalline powders and DMSO solutions at room temperature and 77 K with an MiniScope MS200, (Magnettech Ltd., Berlin, Germany), X-band spectrometer (9.3-9.6 GHz), connected to a PC equipped with a 100 KHz field modulation unit. High resolution mass spectra were recorded on a ThermoScientific (LTQ XLOrbitrap) spectrometer using APCI ionization technique and Orbital Ion Trap mass analyzer (Rockford, IL, USA).
