Figure 1
Perspective views of the crystal structures of CuCr2O4 (left) and MgCr2O4 (right) along the a-axis of the I41/amd cell. CuO4 tetrahedra are drawn in green, MgO4 tetrahedra in grey. In CuCr2O4, the contraction along the c direction due to JT flattening of tetrahedral sites is given by a change of tetrahedral angles. Relevant geometrical parameters are reported.
