Description

The ternary compound Cu2SnTe3 crystallizes in the Imm2 (N circle 44) space group, Z=2, with a=2.833(4) A, b=4.274(1) A, c=6.043(1) A, V=331.5(1) A3. Its structure was refined from X-ray powder diffraction data using the Rietveld method. The refinement of 25 instrumental and structural variables led to Rp=10.2%, Rwp=11.8%, Rexp=7.7%, RB=10.6%, S=1.6 and χ2=2.6, for 5501 step intensities and 163 independent reflections. This compound is isostructural with Cu2GeSe3, and consists of a three-dimensional arrangement of slightly distorted CuTe4 and SnTe4 tetrahedra connected by common corners.
