The crystal structure described by PmS2 crystallizes in the tetragonal P4/nmm space group. Pm(1) is bonded in a 9-coordinate geometry to four equivalent S(1) and five equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to four equivalent Pm(1) atoms. In the second S site, S(2) is bonded to five equivalent Pm(1) atoms to form a mixture of distorted corner and edge-sharing SPm5 trigonal bipyramids. is represented by the CIF card [CIF]
