The compound described by Al2S3 is Corundum structured and crystallizes in the trigonal R-3c space group. Al(1) is bonded to six equivalent S(1) atoms to form a mixture of edge, face, and corner-sharing AlS6 octahedra. The corner-sharing octahedral tilt angles range from 47-59°. S(1) is bonded to four equivalent Al(1) atoms to form a mixture of distorted edge and corner-sharing SAl4 trigonal pyramids. is represented by the CIF file [CIF]
