The structure described by YbAsS crystallizes in the orthorhombic Pnma space group. Yb(1) is bonded to two equivalent As(1) and five equivalent S(1) atoms to form distorted YbAs2S5 square pyramids that share corners with four equivalent Yb(1)As2S5 square pyramids, corners with four equivalent As(1)Yb2As2 trigonal pyramids, edges with six equivalent Yb(1)As2S5 square pyramids, and faces with two equivalent Yb(1)As2S5 square pyramids. As(1) is bonded to two equivalent Yb(1) and two equivalent As(1) atoms to form distorted AsYb2As2 trigonal pyramids that share corners with four equivalent Yb(1)As2S5 square pyramids, corners with six equivalent S(1)Yb5 square pyramids, corners with four equivalent As(1)Yb2As2 trigonal pyramids, and edges with two equivalent S(1)Yb5 square pyramids. S(1) is bonded to five equivalent Yb(1) atoms to form SYb5 square pyramids that share corners with four equivalent S(1)Yb5 square pyramids, corners with six equivalent As(1)Yb2As2 trigonal pyramids, edges with eight equivalent S(1)Yb5 square pyramids, and edges with two equivalent As(1)Yb2As2 trigonal pyramids. is represented by the CIF file [CIF]
