Some Studies in Inorganic Complexes. V. Mercury(II)

Abstract

A study has been made of mercury(II) complexes of ethylenediamine, 1,10-phenanthroline, and 2,2'-dipyridyl. By means of conductance and molecular weight measurements it has been shown that complexes of the type HgX₂.B and HgY.B, in which B is the base, X is halogen or nitrite, and Y is oxalate or sulphate, are 4-covalent non-electrolytes. The absorption spectra of the halogen complexes in the near ultra-violet range are characteristic of the chelate with a shift of absorption to longer wavelengths. Bisphenanthroline and bisdipyridyl complexes of mercury(II) were also investigated.
