and 13C NMR spectroscopy, circular dichroism, UV–vis, and electrospray ionization mass spectrometry. Compounds 1–3, 6, and 7 were also studied by single-crystal X-ray diffraction. Magnetic properties and solid-state high-field electron paramagnetic resonance spectra of 2 over the range of 50–420 GHz were investigated. The complex formation processes of l-Pro-FTSC with nickel(II) and zinc(II) were studied
