Materials Data on Ca(CoS2)2 by Materials Project
Ca(CoS2)2 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Ca2+ is bonded to four equivalent S2- atoms to form CaS4 tetrahedra that share corners with twelve equivalent CoS6 octahedra. The corner-sharing octahedra tilt angles range from 60–65°. All Ca–S bond lengths are 2.61 Å. Co3+ is bonded to six equivalent S2- atoms to form distorted CoS6 octahedra that share corners with six equivalent CaS4 tetrahedra and edges with six equivalent CoS6 octahedra. There are four shorter (2.31 Å) and two longer (2.32 Å) Co–S bond lengths. S2- is bonded to one Ca2+ and three equivalent Co3+ atoms to form a mixture of edge and corner-sharing SCaCo3 tetrahedra.
