Hydrogen bonding and size effects of the cations on the coordination geometry of the metal ions. Tetrahalocobaltates(II) of the N-ethyl-, 2-ethyl- and 4-benzyl-piperidine cations. Crystal and molecular structure of the bis(4-benzylpiperidinium) tetrachlorocobaltate(II).

Some compounds of formula (LH)2(CoX4), where LH= N-ethyl-, 2-ethyl- and 4-benzylpiperidinium cation were synthesized and characterized by means of spectroscopic (UV-vis and vibratiional spectra), and magnetic measurements. For the chlorocobaltate complex with 4-benzylpiperidinium the crystal structure was determined. The far-IR spectra were discussed on the basis of C2 symmetr
