Ir2S3 is Corundum structured and crystallizes in the trigonal R-3c space group. Ir(1) is bonded to six equivalent S(1) atoms to form a mixture of edge, corner, and face-sharing IrS6 octahedra. The corner-sharing octahedral tilt angles range from 47-62°. S(1) is bonded to four equivalent Ir(1) atoms to form a mixture of distorted edge and corner-sharing SIr4 trigonal pyramids.

The corner-sharing octahedral tilt angles range from 47-62°. There are three shorter (2.36 Å) and three longer (2.40 Å) Ir(1)-S(1) bond lengths. S(1) is bonded to four equivalent Ir(1) atoms to form a mixture of distorted edge and corner-sharing SIr4 trigonal pyramids.
