LaC4N2H4Cl3 crystallizes in the orthorhombic Cmme space group. La(1) is bonded in a 8-coordinate geometry to two equivalent N(1), two equivalent Cl(2), and four equivalent Cl(1) atoms. Both La(1)-N(1) bond lengths are 2.89 Å. Both La(1)-Cl(2) bond lengths are 2.79 Å. All La(1)-Cl(1) bond lengths are 2.88 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2), one N(1), and one H(1) atom. The C(1)-C(2) bond length is 1.39 Å. The C(1)-N(1) bond length is 1.34 Å. The C(1)-H(1) bond length is 1.09 Å. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one C(1), one N(1), and one H(2) atom. The C(2)-N(1) bond length is 1.34 Å. The C(2)-H(2) bond length is 1.09 Å. N(1) is bonded in a distorted bent 120 degrees geometry to one La(1), one C(1), and one C(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a water-like geometry to two equivalent La(1) atoms. In the second Cl site, Cl(2) is bonded in a linear geometry to two equivalent La(1) atoms.
