K As As Cl
KAs2Cl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KAs2Cl clusters. K(1) is bonded in an L-shaped geometry to two equivalent As(1) atoms. Both K(1)-As(1) bond lengths are 0.15 Å. As(1) is bonded in an L-shaped geometry to one K(1) and one Cl(1) atom. The As(1)-Cl(1) bond length is 0.15 Å. Cl(1) is bonded in an L-shaped geometry to two equivalent As(1) atoms.
