High-pressure synthesis, crystal structure, and physical properties of mercury-containing transition-metal oxides were introduced from a viewpoint of coordination chemistry of mercury. It is interesting that mercury behaves not only as a cation (Hg2+) but also as a molecule anion (HgO22−) and metal cluster (Hgn). Since mercury is volatile, high-pressure synthesis is an essential technique to produce new mercury-containing compounds.
