The compound described by Ta9(CoS3)2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 3-coordinate geometry to two equivalent Co(1), one S(2), and two equivalent S(1) atoms. In the second Ta site, Ta(2) is bonded to two equivalent Co(1), one S(1), and two equivalent S(2) atoms to form a mixture of distorted edge and corner-sharing TaCo2S3 trigonal bipyramids. Co(1) is bonded in a 9-coordinate geometry to three equivalent Ta(1) and six equivalent Ta(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to two equivalent Ta(1) and two equivalent Ta(2) atoms. In the second S site, S(2) is bonded in a distorted pentagonal planar geometry to one Ta(1) and four equivalent Ta(2) atoms. is represented by the CIF card [CIF]
