The structure described by K2CoS2 crystallizes in the orthorhombic Ibam space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Co(1) and six equivalent S(1) atoms. Co(1) is bonded to four equivalent K(1) and four equivalent S(1) atoms to form distorted face-sharing CoK4S4 tetrahedra. S(1) is bonded in a 8-coordinate geometry to six equivalent K(1) and two equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
