Abstract
The structure of the radical anion salt (RAS) of 7,7,8,8-tetracyanedimethane (TCNQ) with a cation based on 2-amin-5-chloro-pyridine (2-NH2-5-Cl–Py, Am), that is, (N–CH3-2-NH2-5-Cl–Py) (TCNQ) (CH3CN), (I) is presented. Unlike most TCNQ RASs, which contain flat TCNQ particle stacks, RAS I contains practically isolated (TCNQ)\(_{2}^{{2 - }}\) π-dimers with unusually short distances between the planes in the dimers: 3.24 Å. In the RAS I IR spectra special features are observed that correspond to the vibronic interactions of molecular vibrations.中文翻译:
