Abstract

[ES]: La estructura cristalina de la fase a-SnCu2FeS4 ha sido analizada por técnicas de difracción de rayos-X, electrones y Energía Dispersiva de Rayos-X. Este compuesto cristaliza en el sistema tetragonal, grupo espacial P4 (No. 81) with a=c=541,4(4) pm, Z=1 y puede ser descrita como una estructura derivada de la esfalerita. El refinamiento final de la estructura convergió a R(F)=0,060.

[EN]: The crystal structure of the phase a-SnCu2FeS4, has been examined by EDX and electron and X-ray difraction techniques. This compound crystallizes in the tetragonal space group P4 (No. 81) with a=c= 541.4 (4) pm, Z=1, and it is a derivative structure of the basic sphalerite structure. The refinement of the structure converged to the final agreement index R(F)=0.060.
