Pr2Cu2In crystallizes in the tetragonal P4/mbm space group. Pr(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and four equivalent In(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Cu(1), and two equivalent In(1) atoms. In(1) is bonded to eight equivalent Pr(1) and four equivalent Cu(1) atoms to form a mixture of corner and face-sharing InPr8Cu4 cuboctahedra.
Pr2Cu2In crystallizes in the tetragonal P4/mbm space group. Pr(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and four equivalent In(1) atoms. There are two shorter (2.99 Å) and four longer (3.03 Å) Pr(1)-Cu(1) bond lengths. All Pr(1)-In(1) bond lengths are 3.45 Å. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Cu(1), and two equivalent In(1) atoms. The Cu(1)-Cu(1) bond length is 2.55 Å. Both Cu(1)-In(1) bond lengths are 3.10 Å. In(1) is bonded to eight equivalent Pr(1) and four equivalent Cu(1) atoms to form a mixture of corner and face-sharing InPr8Cu4 cuboctahedra.
