• Resumen

  • The new ordered vacancy compound Ag_(3)In_(5)□Te_(9)was synthesized by the melt and annealing technique and its structure was refined from Xray powder diffraction pattern using the Rietveld method. The title compound crystallizes in the tetragonal space group P4̅2c (N◦ 112), with a = 6.3453(2) Å, c = 12.5754(7) Å, V = 506.32(4) Å^(3) . The refinement of 23 instrumental and structural parameters led to R_(p) = 5.4%, R_(wp) = 5.8%, R_(exp) = 5.1%, S = 1.1. This ternary compound is isostructural with Cu_(3) In_(5)□Te_(9)and have a defect adamantane structure.
