Structural chemistry of binary and ternary hafnium-rich tellurides.

摘要

hile ternary group V tellurides have received much attention recently, the chemistry of the group IV transition metal tellurides, especially that of hafnium, has remained virtually unexplored. Brewer's ideas concerning strong, intermetallic interactions have served as a synthetic guide in the preparation of several structurally unique compounds. When possible the electronic transport properties have been measured. Extended Huckel calculations serve to rationalize the observed structural features and properties.;A family of isostructural ternary tellurides of the composition ;The synthesis of the new ternary hafnium tellurides ;The Hf-rich region of the Hf-Te binary system was also investigated in the course of the studies on ternary systems. Three new phases have been synthesized.
