The structure described by BaS2 crystallizes in the monoclinic C2/c space group. Ba(1) is bonded to eight equivalent S(1) atoms to form BaS8 hexagonal bipyramids that share corners with four equivalent Ba(1)S8 hexagonal bipyramids, corners with eight equivalent S(1)Ba4S trigonal bipyramids, and edges with ten equivalent Ba(1)S8 hexagonal bipyramids. S(1) is bonded to four equivalent Ba(1) and one S(1) atom to form distorted SBa4S trigonal bipyramids that share corners with four equivalent Ba(1)S8 hexagonal bipyramids, corners with eighteen equivalent S(1)Ba4S trigonal bipyramids, and edges with five equivalent S(1)Ba4S trigonal bipyramids. is represented by the CIF card [CIF]
