Materials Data on La2C2Cl by Materials Project
La2C2Cl crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. La3+ is bonded to five equivalent C+2.50- and three equivalent Cl1- atoms to form a mixture of distorted edge, face, and corner-sharing LaC5Cl3 hexagonal bipyramids. There are a spread of La–C bond distances ranging from 2.40–2.87 Å. There are a spread of La–Cl bond distances ranging from 3.18–3.29 Å. C+2.50- is bonded in a 6-coordinate geometry to five equivalent La3+ and one C+2.50- atom. The C–C bond length is 1.36 Å. Cl1- is bonded to six equivalent La3+ atoms to form distorted edge-sharing ClLa6 octahedra.
