Crystal structure of the RAgTe2 (R=Y, Tb, Dy, Ho and Er) compounds

Crystal structure of the TmAgTe2 compound

“…The Tm-Te distances agree well with the respective R-Te distances of the RAgTe 2 compounds (R = Y, Tb, Dy, Ho and Er) investigated in Ref. [3]. At the same time the Ag-Te distances of the TmAgTe 2 compound are slightly longer when compared with the respective distances of the RAgTe 2 compounds (R = Y, Tb, Dy, Ho and Er).…”

“…These octahedra connected by faces form the columns along z-axis. The Te atoms in the structure of the ErAgTe 2 compound (space group P42 1 m) [3] are also stacked in a close-packed arrangement with the layers in the sequence AB. Half of the octahedral interstices are occupied by the Er atoms.…”

“…Complete crystal structure determination of the RAgTe 2 compounds (R = Y, Tb, Dy, Ho and Er) (space group P42 1 m) has been reported recently in Ref. [3].…”

Investigation of the R2Te3–M2Te–PbTe (R=Tb, Dy; M=Cu, Ag) systems at 770K

“…[14] using X-ray powder diffraction. Single crystal reinvestigation of the RAgTe 2 (R = Tb, Dy) compounds was performed in present paper.…”

“…[13] in the R 2 Te 3 -Cu 2 Te (R = Tb, Dy) sections has been reported in literature. The crystal structure of the RAgTe 2 compounds (ErAgTe 2 structure type, space group P42 1 m, a = 0.71466 nm, c = 0.46108 nm for TbAgTe 2 ; a = 0.71287 nm, c = 0.45955 nm for DyAgTe 2 ) has been reported recently [14]. No compounds in the systems R 2 Te 3 -PbTe (R = Tb, Dy) and M 2 Te-PbTe (M = Cu, Ag) have been reported in literature.…”
