The Infra-red Spectrum of the Thyocyanate Group in the Pyridine Complexes of Cu(Il), Ni(II) and Co(II)

Abstract

The compounds Co (Py) 4Cl2, Co (Py) 2Cl2, Cu (Py)2(NCS) 2, Co (Py) 4 (NCS) 2 and Ni (Py) 4 (NCS) 2 were synthesized and their I.R. spectra recorded. The assignment of the vibrational frequencies is given with reference to the crystal structure of these compounds.
