Abstract

The crystal structures of ternary compds. RPt3- xSi1- y(R=Y, Tb, Dy, Ho, Er, Tm, Yb) have been elucidated from X-ray single crystal CCD data. All compds. are isotypic and crystallize in the tetragonal space group P4/mbm. The general formula RPt3- xSi1- y arises from defects: x0.20, y0.14. The crystal structure of RPt3- xSi1- y can be considered as a packing of four types of building blocks which derive from the CePt3B-type unit cell by various degrees of distortion and Pt, Si-defects.
