Chemistry of polynuclear compounds. Part X. Interaction of the compounds Fe(CO)4(HgY)2(where Y = Cl or Br) with halide ions (X) and with amines

Abstract

Complex ions of the type [Fe(CO)4(HgY)2X] where X or Y = Cl, Br, or l have been prepared as their quaternary ammonium, phosphonium, and arsonium salts. The salts are uni-univalent electrolytes in nitrobenzene and appear to be formed by both halide-addition and -exchange reactions from interaction of the appropriate halide (X) with Fe(CO)4(HgY)2(where Y = Cl or Br). The far-infrared spectra of the complexes have been recorded in the range 50–234 cm.–1 and are considered in relation to the proposed structures. Primary, secondary, and heterocyclic amines reversibly add to Fe(CO)4(HgCl)2 to form mono- or bis-adducts depending upon the amine employed. The amine-adducts are non-electrolytes in nitrobenzene and their infrared spectra are reported.
