Structural Transformation in Some Chevrel Phase Compounds: ZnMo5S6, ZnMo5Se6 and CuO.7Mo3Se4.

摘要

Low temperature x-ray powder diffraction and electrical resistivity experiments show that the Chevrel phase compounds ZnMo5S6, ZnMo5Se6 and CuO.7Mo3Se4 are structurally unstable near or below room temperature. The binary compounds Mo3S4, Mo3Se4 and Mo3Te4 are stable to 6K. (Author)
