K2Hg2Se3: Large-Scale Synthesis of a Photoconductor Material Prototype with a Columnar Polyanionic Substructure

“…The chemistry of mercury is accompanied by a fascinating structural diversity, − but dealing with mercury is often neglected for its toxicity . However, whereas organic compounds of mercury are usually volatile and thus easily inhaled or absorbed via the skin, most inorganic compounds resemble salts which are fairly easy to handle if care is taken to avoid contamination of skin or inhalation of dusts.…”
