Abstract
We have studied the tetrahalocobaltate complexes of the morpholinium and piperidinium cations and of the 1-methyl- and 2-methyl-piperazinium dications. Their magnetic moments and electronic spectra suggest the presence of complexes having distorted tetrahedral symmetries and their IR spectra (4000-400 cm-1) indicate that the hydrogen bonding interactions are partly responsible for their distortion.
