Cerium intermetallics with TiNiSi-type structure

Abstract

Abstract Intermetallic compounds with the equiatomic composition Ce TX that crystallize with the orthorhombic TiNiSi-type structure can be synthesized with electron-rich transition metals ( T ) and X = Zn, Al, Ga, Si, Ge, Sn, As, Sb, and Bi. The present review focusses on the crystal chemistry and chemical bonding of these Ce TX phases and on their physical properties, 119 Sn and 121 Sb Mössbauer spectra, high-pressure effects, hydrogenation reactions and the formation of solid solutions in order to elucidate structure–property relationships. This paper is the final one of a series of four reviews on equiatomic intermetallic cerium compounds [Part I: Z. Naturforsch . 2015 , 70b , 289; Part II: Z.
