Abstract

The Ph3E-E'Me3 (E= Si, Ge, Sn; E'= Si, Ge, Sn) compounds exhibit two morphotropic steps in the crystalline state: a [E= E'= Si; E= Si, E'= Ge; E= Ge, E'= Si, E= E'= Ge (space group P 3̄)]→ b [E= Ge, E'= Sn; E= Sn, E'= Ge (space group Pna 21)]→ c [E= E'= Sn (space group P 3̄)]. Ph3Sn-SnMe3 reverts to group a. Due to the long Sn-Sn bond, it is not isometric, and therefore not isostructural, with the group a compounds; the relaxed relationship is termed ...
