LaVCl2 is Heusler structured and crystallizes in the trigonal R3m space group. La(1) is bonded in a distorted linear geometry to one Cl(1) and four equivalent Cl(2) atoms. The La(1)-Cl(1) bond length is 2.69 Å. There is one shorter (2.69 Å) and three longer (3.24 Å) La(1)-Cl(2) bond lengths. V(1) is bonded to one Cl(1) and three equivalent Cl(2) atoms to form distorted corner-sharing VCl4 trigonal pyramids. The V(1)-Cl(1) bond length is 2.69 Å. All V(1)-Cl(2) bond lengths are 2.92 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 2-coordinate geometry to one La(1) and one V(1) atom. In the second Cl site, Cl(2) is bonded in a 7-coordinate geometry to four equivalent La(1) and three equivalent V(1) atoms.
