However, all crystal structural parameters of this compound were recently obtained from Rietveld refinement of the X-ray powder diffraction patterns [21]. This analysis indicates that Cu2SnTe3 crystallizes in an orthorhombic cell, space group Imm 2 View the MathML source, with two molecular units per unit cell and refined lattice constants a=1.2833(4),b=0.4274(1), and View the MathML source. It was also found [21] that Cu2SnTe3 is isostructural with Cu2GeSe3 and Cu2GeTe3, and consists of a three-dimensional arrangement of slightly distorted CuTe4 and SnTe4 tetrahedra connected by common corners. The Cu–Te and Sn–Te mean bond distances are 0.262(2) and 0.261(2) nm, respectively.
