Abstract

High-pressure crystal chemistry of transition metal diantimonides is discussed. Two types of pressure-induced phase transitions, marcasite-type to CuAl2-type and marcasite-type to pararammelsbergite-type, occur in this family. The former is found in CrSb2 and the transition is accompanied by a change in bonding character from the mixed ionic and covalent to metallic. The latter is found in NiSb2 and can be explained by effective packing of NiSb6, octahedra. The local environment of nickel atom remains unchanged during the transition. The phase transition sequences in transition metal diantimonides, together with other dipnictides and dichalcogenides, are schematically summarized.
