Bowmaker, Graham A. published the artcileVibrational spectra of adducts of iodine monochloride with some pyridine bases, Safety of Pyridine Iodochloride complex, the publication is Australian Journal of Chemistry (1980), 33(8), 1743-51, database is CAplus.
A series of mol. adducts, L-ICl, where L = pyridine or a pyridine derivative, were prepared and the solid state spectra examined by Raman and far-IR spectroscopy. Assignments of the modes ν(I-Cl) 240-300 cm-1 and ν(N-I) 90-180 cm-1 and force constant calculations in a simple 3-center model yield information on structure and bonding related to the nature of the pyridine donor. Several ionic products containing the ICl2– ion were encountered.
Australian Journal of Chemistry published new progress about 6443-90-9. 6443-90-9 belongs to iodides-buliding-blocks, auxiliary class Pyridines, name is Pyridine Iodochloride complex, and the molecular formula is C5H5ClIN, Safety of Pyridine Iodochloride complex.
