Testing thermal stability of orthorhombic GdCuP2.16 structure

Thermal stability with respect to a structural transformation and the crystal structure of the orthorhombic gadolinium copper phosphide GdCuP2.16 was investigated using powder diffraction techniques. The structure was refined from the data collected at room temperature to yield Pmm2 space group, a=5.3284(1), b=5.3868(1) and c=9.7486(2) Å. The refinement results agree well with the single crystal results [J. Solid State Chem. 155 (2000) 259]. …
