In2S3 is Corundum structured and crystallizes in the trigonal R-3c space group. In(1) is bonded to six equivalent S(1) atoms to form a mixture of distorted edge, face, and corner-sharing InS6 octahedra. The corner-sharing octahedral tilt angles range from 48-62°. S(1) is bonded to four equivalent In(1) atoms to form a mixture of distorted edge and corner-sharing SIn4 trigonal pyramids.

In(1) is bonded to six equivalent S(1) atoms to form a mixture of distorted edge, face, and corner-sharing InS6 octahedra. The corner-sharing octahedral tilt angles range from 48-62°. There are three shorter (2.57 Å) and three longer (2.71 Å) In(1)-S(1) bond lengths. S(1) is bonded to four equivalent In(1) atoms to form a mixture of distorted edge and corner-sharing SIn4 trigonal pyramids.
