The material structure described by LiCoAs is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Li(1) is bonded in a 9-coordinate geometry to four equivalent Co(1) and five equivalent As(1) atoms. Co(1) is bonded in a 8-coordinate geometry to four equivalent Li(1) and four equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to five equivalent Li(1) and four equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
