Pa2S3 is Corundum structured and crystallizes in the trigonal R-3c space group. Pa(1) is bonded to six equivalent S(1) atoms to form a mixture of corner, edge, and face-sharing PaS6 octahedra. The corner-sharing octahedral tilt angles range from 47-56°. S(1) is bonded to four equivalent Pa(1) atoms to form a mixture of distorted corner and edge-sharing SPa4 trigonal pyramids.

The corner-sharing octahedral tilt angles range from 47-56°. There are three shorter (2.72 Å) and three longer (2.75 Å) Pa(1)-S(1) bond lengths. S(1) is bonded to four equivalent Pa(1) atoms to form a mixture of distorted corner and edge-sharing SPa4 trigonal pyramids.
