The crystal structure described by Pm2S3 is Corundum structured and crystallizes in the trigonal R-3c space group. Pm(1) is bonded to six equivalent S(1) atoms to form a mixture of edge, face, and corner-sharing PmS6 octahedra. The corner-sharing octahedral tilt angles range from 48-63°. S(1) is bonded to four equivalent Pm(1) atoms to form a mixture of distorted edge and corner-sharing SPm4 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
