LaC10N2H8Cl3 crystallizes in the orthorhombic Pcca space group. La(1) is bonded in a 8-coordinate geometry to two equivalent N(1), two equivalent Cl(1), and four equivalent Cl(2) atoms. Both La(1)-N(1) bond lengths are 2.79 Å. Both La(1)-Cl(1) bond lengths are 2.84 Å. There are two shorter (2.83 Å) and two longer (2.92 Å) La(1)-Cl(2) bond lengths. There are five inequivalent C sites. In the first C site, C(1) is bonded in a distorted trigonal planar 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 1.35 Å. The C(1)-H(1) bond length is 1.09 Å. In the second C site, C(5) is bonded in a distorted single-bond geometry to one C(3), one C(4), and one H(4) atom. The C(5)-C(3) bond length is 1.40 Å. The C(5)-C(4) bond length is 1.39 Å. The C(5)-H(4) bond length is 1.09 Å.
