Materials Data on Ce2MgCu2 by Materials Project
Ce2Cu2Mg crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Mg is bonded to eight equivalent Ce and four equivalent Cu atoms to form a mixture of distorted corner and face-sharing MgCe8Cu4 cuboctahedra. All Mg–Ce bond lengths are 3.42 Å. All Mg–Cu bond lengths are 3.07 Å. Ce is bonded in a 6-coordinate geometry to four equivalent Mg and six equivalent Cu atoms. There are two shorter (2.92 Å) and four longer (2.98 Å) Ce–Cu bond lengths. Cu is bonded in a 9-coordinate geometry to two equivalent Mg, six equivalent Ce, and one Cu atom. The Cu–Cu bond length is 2.65 Å.
