Abstract
ONE of the most common heavy-atom groups now being used in the analysis of protein structures by the isomorphous replacement method is a mercuri-iodida ion derived from K2HgI4. The nature of this ion arid the mechanism of its attachment to protein molecules are, however, still unknown. It has been suggested1 that the mercuri-iodide-protein complexes may be related to the complexes formed by mercuric iodide with dialkyl thio-ethers2 and we have accordingly examined a number of these and related compounds by X-ray diffraction methods.
