The structure described by Co4H crystallizes in the trigonal P-3m1 space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 3-coordinate geometry to three equivalent Co(2) and three equivalent H(1) atoms. In the second Co site, Co(2) is bonded to three equivalent Co(1) and nine equivalent Co(2) atoms to form CoCo12 cuboctahedra that share corners with six equivalent Co(2)Co12 cuboctahedra, corners with three equivalent H(1)Co6 octahedra, edges with twelve equivalent Co(2)Co12 cuboctahedra, edges with three equivalent H(1)Co6 octahedra, and faces with twelve equivalent Co(2)Co12 cuboctahedra. The corner-sharing octahedral tilt angles are 17°. H(1) is bonded to six equivalent Co(1) atoms to form HCo6 octahedra that share corners with six equivalent Co(2)Co12 cuboctahedra, edges with six equivalent Co(2)Co12 cuboctahedra, and edges with six equivalent H(1)Co6 octahedra. is represented by the Crystallographic Information File (CIF) [CIF]
