La Cd Cd As
LaCd2As crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaCd2As clusters. La(1) is bonded in an L-shaped geometry to two equivalent Cd(1) atoms. Both La(1)-Cd(1) bond lengths are 0.62 Å. Cd(1) is bonded in a single-bond geometry to one La(1) and one As(1) atom. The Cd(1)-As(1) bond length is 1.76 Å. As(1) is bonded in a 2-coordinate geometry to two equivalent Cd(1) atoms.
