Iodomercurates (II) of Manganese (II), Cobalt (II), Nickel (II) and ɛ-caprolactam Complexes

Iodomercurates(II) of coordination compounds of transition metals [M(ɛ-C6H11NO)6][Hg2I6] (M – Mn2+, Co2+, Ni2+) and ɛ-caprolactam were synthesized. The obtained compounds were studied by the methods of gravimetric, IR-spectroscopic and X-ray diffraction analysis.
