“…Moreover, the Zr d electrons, which do not enter into heteronuclear The Zr-Te interactions would give rise to an increase in density by 4.5% compared with 7.644 g cm~3 for ZrTe ( WC) and would leave ZrTe (NiAs) as the dens est of all known compounds in the Zr-Te system. In view of the weaker Zr-Zr interactions on one hand and the particularly well tuned heteronuclear inter actions on the other hand, a reduction in zirconium content at high temperatures -as actually observed [7,8 ] -would come as a natural response to lower the density and to gain configurational entropy with out a substantial loss of bonding interactions.…”

“…However, for the high tempera ture phase, metal deficiency is observed [7,8 ]. In an attempt to gain some understanding of this phe nomenon, extended Hiickel calculations were car ried out.…”

“…[42] For ZrTe (NiAs), reported lattice parameters [19] (a 396.2, c 669.3 pm) for a nominal composition of 52 atomic % Te were used. In hypothetical Zr 5 Te 6 model a, NiAs-type ZrTe atomic coordinates and lattice parameters (3a  3a  1c) were used.…”

“…In the metal-rich part, Zr 5 Te 4 , [12,15,16] Zr 3 Te [16,17] and Zr 2 Te [18] have been reported. In addition to an earlier partial phase diagram, [19] a tentative phase diagram of the system was published lately, [20] which contained some valuable hints for preparative work.…”

“…In the metal-deficient phases, however, the structures with NaCl-type supercells dominate with partial or complete ordering of the vacancies. The corresponding tellurides do not seem to have extended homogeneity ranges, with the exception of Zr \V Te with a defect NiAs-type structure (x"0-0.5) (6). Nothing is explicitly reported in the literature about the occurrence of nonstoichiometric lanthanide tellurides.…”
