EuZnIn3 crystallizes in the tetragonal I4mm space group. Eu(1) is bonded in a 16-coordinate geometry to four equivalent Zn(1), four equivalent In(2), and eight equivalent In(1) atoms. Zn(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), one In(2), and four equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 2-coordinate geometry to four equivalent Eu(1), two equivalent Zn(1), and two equivalent In(2) atoms. In the second In site, In(2) is bonded in a distorted single-bond geometry to four equivalent Eu(1), one Zn(1), and four equivalent In(1) atoms.
EuZnIn3 crystallizes in the tetragonal I4mm space group. Eu(1) is bonded in a 16-coordinate geometry to four equivalent Zn(1), four equivalent In(2), and eight equivalent In(1) atoms. All Eu(1)-Zn(1) bond lengths are 3.59 Å. All Eu(1)-In(2) bond lengths are 3.56 Å. There are four shorter (3.67 Å) and four longer (3.90 Å) Eu(1)-In(1) bond lengths. Zn(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), one In(2), and four equivalent In(1) atoms. The Zn(1)-In(2) bond length is 2.59 Å. All Zn(1)-In(1) bond lengths are 2.78 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 2-coordinate geometry to four equivalent Eu(1), two equivalent Zn(1), and two equivalent In(2) atoms. Both In(1)-In(2) bond lengths are 3.00 Å. In the second In site, In(2) is bonded in a distorted single-bond geometry to four equivalent Eu(1), one Zn(1), and four equivalent In(1) atoms.
