NdLaC4 crystallizes in the tetragonal P4/mmm space group. Nd(1) is bonded in a distorted q4 geometry to two equivalent C(1) and eight equivalent C(2) atoms. La(1) is bonded in a distorted q4 geometry to two equivalent C(2) and eight equivalent C(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 6-coordinate geometry to one Nd(1), four equivalent La(1), and one C(1) atom. In the second C site, C(2) is bonded in a 6-coordinate geometry to four equivalent Nd(1), one La(1), and one C(2) atom.
NdLaC4 crystallizes in the tetragonal P4/mmm space group. Nd(1) is bonded in a distorted q4 geometry to two equivalent C(1) and eight equivalent C(2) atoms. Both Nd(1)-C(1) bond lengths are 2.61 Å. All Nd(1)-C(2) bond lengths are 2.83 Å. La(1) is bonded in a distorted q4 geometry to two equivalent C(2) and eight equivalent C(1) atoms. Both La(1)-C(2) bond lengths are 2.61 Å. All La(1)-C(1) bond lengths are 2.83 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 6-coordinate geometry to one Nd(1), four equivalent La(1), and one C(1) atom.
