N2 - The title compound, UCu0.60(4)Sb2, crystallizes in the tetra-gonal space group P4/nmm. The U atom and one independent Sb atom have 4mm site symmetry, whereas the Cu atom and the other Sb atom have 2m site symmetry. Zigzag USb sheets stack perpendicular to the c axis. These sheets are separated by square-planar nets of Sb atoms and Cu atoms. The length of the a axis for UCu x Sb2 is invariant to x, whereas there is a linear relationship between Cu occupancy and the length of the c axis (following Vegards Law) that holds for x between 0 and 1. This is explained in terms of the crystal structure.
