CoSbAs2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CoSbAs2 clusters. Co(1) is bonded in an L-shaped geometry to two equivalent As(1) atoms. Both Co(1)-As(1) bond lengths are 0.40 Å. Sb(1) is bonded in a 2-coordinate geometry to two equivalent As(1) atoms. Both Sb(1)-As(1) bond lengths are 0.89 Å. As(1) is bonded in a distorted single-bond geometry to one Co(1) and one Sb(1) atom.
