PrAsSe crystallizes in the orthorhombic Pnma space group. Pr(1) is bonded in a 9-coordinate geometry to four equivalent As(1) and five equivalent Se(1) atoms. As(1) is bonded in a 6-coordinate geometry to four equivalent Pr(1) and two equivalent As(1) atoms. Se(1) is bonded to five equivalent Pr(1) atoms to form a mixture of distorted edge and corner-sharing SePr5 trigonal bipyramids.
