The title compounds, for short Ag 6 (tsac) 6 (1) and [Cu 4 (tsac) 4 (MeCN) 2 ]·2MeCN (2), were prepared by the reaction of thiosaccharin with Ag(I) or Cu(II) salts in different solvents. The new complexes were characterized by FT-IR, Raman, UV–Vis and NMR spectroscopy. Their crystal and molecular structures were determined by X-ray diffraction methods. The structures...
A new metastable excited state (metastable state I, MSI) was detected when (η-cyclopentadienyl)nitrosylnickel, Ni(C 5 H 5 )NO, was irradiated at 77 K with 488.0 and 514.5 nm Ar + -laser lines. The infrared spectra of metastable states I (MSI) and metastable state II (MSII) are characterized by down-shifts of the ν(NO) bands (260 cm −1 for MSI, and 460 cm −1 ...
